With tqdm (conda install tqdm or pip install tqdm) you can add a progress meter to your loops in a second:

from time import sleep
from tqdm import tqdm
for i in tqdm(range(10)):
    sleep(3)

 60%|██████    | 6/10 [00:18<00:12,  0.33 it/s]

Also, there is a notebook version:

from tqdm.notebook import tqdm
for i in tqdm(range(100)):
    sleep(3)

You can use tqdm.auto instead of tqdm.notebook to work in both a terminal and notebooks.

tqdm.contrib contains some helper functions to do things like enumerate, map, and zip. There are concurrent maps in tqdm.contrib.concurrent.

You can even get progress sent to your phone after disconnecting from a jupyter notebook using tqdm.contrib.telegram or tqdm.contrib.discord.

Use alive-progress, the coolest progress bar ever! Just pip install alive-progress and you're good to go!

To use any progress bar effectively, i.e. gaining both a percentage of completion and an ETA, you need to be able to tell it the total number of items. Then alive-progress will keep track of where your processing currently is, and how long it will take!
Don't worry if you can't estimate the total, alive-progress will still work.

To use it, you can either drive alive-progress' bar directly:

def compute():
    with alive_bar(1000) as bar:  # your expected total
        for item in items:        # the original loop
            print(item)           # your actual processing here
            bar()                 # call `bar()` at the end


compute()

Or, if you prefer to keep the codes isolated, just insert a yield in your processing code (to mark when an item has been processed), then drive the alive-progress' bar like this:

def compute():
    for item in items:
        print(item)
        yield                  # simply insert this :)


with alive_bar(1000) as bar:
    for i in compute():
        bar()

Either way, you'll get an awesome and animated progress bar!

And it supports a LOT OF advanced options right out of the box!!

Disclosure: I'm the proud author of alive-progress, which has 5K+ ⭐️ on github!
Read the documentation at https://github.com/rsalmei/alive-progress to get to know all the advanced features.

Behold some more animations it can do in both spinner and bar widgets:

It also works on Jupyter Notebooks!

You can even design your own animations!!

No external packages. A ready-made piece of code.

You can customize bar progress symbol "#", bar size, text prefix etc.

Python 3.6+ (f-string) with Time Remaining estimate

import sys
import time

def progressbar(it, prefix="", size=60, out=sys.stdout): # Python3.6+
    count = len(it)
    start = time.time() # time estimate start
    def show(j):
        x = int(size*j/count)
        # time estimate calculation and string
        remaining = ((time.time() - start) / j) * (count - j)        
        mins, sec = divmod(remaining, 60) # limited to minutes
        time_str = f"{int(mins):02}:{sec:03.1f}"
        print(f"{prefix}[{u'█'*x}{('.'*(size-x))}] {j}/{count} Est wait {time_str}", end='\r', file=out, flush=True)
    show(0.1) # avoid div/0 
    for i, item in enumerate(it):
        yield item
        show(i+1)
    print("\n", flush=True, file=out)

[████████████████████████████.........................] 24/50 Est wait 00:05.3

Usage:

import time    
for i in progressbar(range(15), "Computing: ", 40):
    time.sleep(0.1) # any code you need

• Doesn't require a second thread. Some solutions/packages above require.

• Works with any iterable it means anything that len() can be used on. A list, a dict of anything for example ['a', 'b', 'c' ... 'g']

• Works with generators only have to wrap it with a list(). For example for i in progressbar(list(your_generator), "Computing: ", 40): Unless the work is done in the generator. In that case you need another solution (like tqdm).

You can also change output by changing out to sys.stderr for example.

Python 3.3+

import sys
def progressbar(it, prefix="", size=60, out=sys.stdout): # Python3.3+
    count = len(it)
    def show(j):
        x = int(size*j/count)
        print("{}[{}{}] {}/{}".format(prefix, "#"*x, "."*(size-x), j, count), 
                end='\r', file=out, flush=True)
    show(0)
    for i, item in enumerate(it):
        yield item
        show(i+1)
    print("\n", flush=True, file=out)

Python 2 (old-code)

import sys
def progressbar(it, prefix="", size=60, out=sys.stdout):
    count = len(it)
    def show(j):
        x = int(size*j/count)
        out.write("%s[%s%s] %i/%i\r" % (prefix, u"#"*x, "."*(size-x), j, count))
        out.flush()        
    show(0)
    for i, item in enumerate(it):
        yield item
        show(i+1)
    out.write("\n")
    out.flush()

The above suggestions are pretty good, but I think most people just want a ready made solution, with no dependencies on external packages, but is also reusable.

I got the best points of all the above, and made it into a function, along with a test cases.

To use it, just copy the lines under "def update_progress(progress)" but not the test script. Don't forget to import sys. Call this whenever you need to display or update the progress bar.

This works by directly sending the "\r" symbol to console to move cursor back to the start. "print" in python does not recongise the above symbol for this purpose, hence we need 'sys'

import time, sys

# update_progress() : Displays or updates a console progress bar
## Accepts a float between 0 and 1. Any int will be converted to a float.
## A value under 0 represents a 'halt'.
## A value at 1 or bigger represents 100%
def update_progress(progress):
    barLength = 10 # Modify this to change the length of the progress bar
    status = ""
    if isinstance(progress, int):
        progress = float(progress)
    if not isinstance(progress, float):
        progress = 0
        status = "error: progress var must be float\r\n"
    if progress < 0:
        progress = 0
        status = "Halt...\r\n"
    if progress >= 1:
        progress = 1
        status = "Done...\r\n"
    block = int(round(barLength*progress))
    text = "\rPercent: [{0}] {1}% {2}".format( "#"*block + "-"*(barLength-block), progress*100, status)
    sys.stdout.write(text)
    sys.stdout.flush()


# update_progress test script
print "progress : 'hello'"
update_progress("hello")
time.sleep(1)

print "progress : 3"
update_progress(3)
time.sleep(1)

print "progress : [23]"
update_progress([23])
time.sleep(1)

print ""
print "progress : -10"
update_progress(-10)
time.sleep(2)

print ""
print "progress : 10"
update_progress(10)
time.sleep(2)

print ""
print "progress : 0->1"
for i in range(101):
    time.sleep(0.1)
    update_progress(i/100.0)

print ""
print "Test completed"
time.sleep(10)

This is what the result of the test script shows (The last progress bar animates):

progress : 'hello'
Percent: [----------] 0% error: progress var must be float
progress : 3
Percent: [##########] 100% Done...
progress : [23]
Percent: [----------] 0% error: progress var must be float

progress : -10
Percent: [----------] 0% Halt...

progress : 10
Percent: [##########] 100% Done...

progress : 0->1
Percent: [##########] 100% Done...
Test completed

Try progress from https://pypi.python.org/pypi/progress.

from progress.bar import Bar

bar = Bar('Processing', max=20)
for i in range(20):
    # Do some work
    bar.next()
bar.finish()

The result will be a bar like the following:

Processing |#############                   | 42/100

for a similar application (keeping track of the progress in a loop) I simply used the python-progressbar:

Their example goes something like this,

from progressbar import *               # just a simple progress bar


widgets = ['Test: ', Percentage(), ' ', Bar(marker='0',left='[',right=']'),
           ' ', ETA(), ' ', FileTransferSpeed()] #see docs for other options

pbar = ProgressBar(widgets=widgets, maxval=500)
pbar.start()

for i in range(100,500+1,50):
    # here do something long at each iteration
    pbar.update(i) #this adds a little symbol at each iteration
pbar.finish()
print

I like Brian Khuu's answer for its simplicity and not needing external packages. I changed it a bit so I'm adding my version here:

import sys
import time


def updt(total, progress):
    """
    Displays or updates a console progress bar.

    Original source: https://stackoverflow.com/a/15860757/1391441
    """
    barLength, status = 20, ""
    progress = float(progress) / float(total)
    if progress >= 1.:
        progress, status = 1, "\r\n"
    block = int(round(barLength * progress))
    text = "\r[{}] {:.0f}% {}".format(
        "#" * block + "-" * (barLength - block), round(progress * 100, 0),
        status)
    sys.stdout.write(text)
    sys.stdout.flush()


runs = 300
for run_num in range(runs):
    time.sleep(.1)
    updt(runs, run_num + 1)

It takes the total number of runs (total) and the number of runs processed so far (progress) assuming total >= progress. The result looks like this:

[#####---------------] 27%

I've just made a simple progress class for my needs after searching here for a equivalent solution. I thought I might a well post it.

from __future__ import print_function
import sys
import re


class ProgressBar(object):
    DEFAULT = 'Progress: %(bar)s %(percent)3d%%'
    FULL = '%(bar)s %(current)d/%(total)d (%(percent)3d%%) %(remaining)d to go'

    def __init__(self, total, width=40, fmt=DEFAULT, symbol='=',
                 output=sys.stderr):
        assert len(symbol) == 1

        self.total = total
        self.width = width
        self.symbol = symbol
        self.output = output
        self.fmt = re.sub(r'(?P<name>%\(.+?\))d',
            r'\g<name>%dd' % len(str(total)), fmt)

        self.current = 0

    def __call__(self):
        percent = self.current / float(self.total)
        size = int(self.width * percent)
        remaining = self.total - self.current
        bar = '[' + self.symbol * size + ' ' * (self.width - size) + ']'

        args = {
            'total': self.total,
            'bar': bar,
            'current': self.current,
            'percent': percent * 100,
            'remaining': remaining
        }
        print('\r' + self.fmt % args, file=self.output, end='')

    def done(self):
        self.current = self.total
        self()
        print('', file=self.output)

Example :

from time import sleep

progress = ProgressBar(80, fmt=ProgressBar.FULL)

for x in xrange(progress.total):
    progress.current += 1
    progress()
    sleep(0.1)
progress.done()

Will print the following:

[======== ] 17/80 ( 21%) 63 to go

You can use tqdm:

from tqdm import tqdm

with tqdm(total=100, desc="Adding Users", bar_format="{l_bar}{bar} [ time left: {remaining} ]") as pbar:
    for i in range(100):
        time.sleep(3)
        pbar.update(1)

In this example the progress bar is running for 5 minutes and it is shown like that:

Adding Users:   3%|█████▊                                     [ time left: 04:51 ]                                                                                                        

You can change it and customize it as you like.

I really like the python-progressbar, as it is very simple to use.

For the most simple case, it is just:

import progressbar
import time

progress = progressbar.ProgressBar()
for i in progress(range(80)):
    time.sleep(0.01)

The appearance can be customized and it can display the estimated remaining time. For an example use the same code as above but with:

progress = progressbar.ProgressBar(widgets=[progressbar.Bar('=', '[', ']'), ' ',
                                            progressbar.Percentage(), ' ',
                                            progressbar.ETA()])

A simple oneliner (no imports, tqdm)

K = 628318
for k in range(K):
    # your stuff
    print(end="\r|%-80s|" % ("="*(80*(k+1)//K)))

|=====================================================================       |

80 is the length of the bar. Eventually you want a final print().

It can be also put into a convencience function. Along with yield, one can emulate the behaviour of tqdm:

def progbar(iterobj):
    K = len(iterobj)
    for k, obj in enumerate(iterobj):
        print(end="\r|%-80s|" % ("="*(80*(k+1)//K)))
        yield obj
    print()
    raise StopIteration

for k in progbar(range(628318)):
    # your stuff
    pass

And not to forget the digital progress indicator:

K = 628318
for k in range(K):
    # your stuff
    print(end=f"\r{(k+1)/K*100:6.2f} %")

 94.53 %

It is not to difficult to combine both, if needed.

The keys are the "Carriage Return" \r and the suppression of the default end="\n" in print.

Use this library: fish (GitHub).

Usage:

>>> import fish
>>> while churning:
...     churn_churn()
...     fish.animate()

Have fun!

If it is a big loop with a fixed amount of iterations that is taking a lot of time you can use this function I made. Each iteration of loop adds progress. Where count is the current iteration of the loop, total is the value you are looping to and size(int) is how big you want the bar in increments of 10 i.e. (size 1 =10 chars, size 2 =20 chars)

import sys
def loadingBar(count,total,size):
    percent = float(count)/float(total)*100
    sys.stdout.write("\r" + str(int(count)).rjust(3,'0')+"/"+str(int(total)).rjust(3,'0') + ' [' + '='*int(percent/10)*size + ' '*(10-int(percent/10))*size + ']')

example:

for i in range(0,100):
     loadingBar(i,100,2)
     #do some code 

output:

i = 50
>> 050/100 [==========          ]

pip install progressbar2

^{Use enumerate(...progressbar(max_value=...) + this in case you want to use it as a download progressbar}

When running in jupyter notebooks use of normal tqdm doesn't work, as it writes output on multiple lines. Use this instead:

import time
from tqdm.notebook import tqdm

for i in tqdm(range(100)):
    time.sleep(0.5)

You can also use enlighten. The main advantage is you can log at the same time without overwriting your progress bar.

import time
import enlighten

manager = enlighten.Manager()
pbar = manager.counter(total=100)

for num in range(1, 101):
    time.sleep(0.05)
    print('Step %d complete' % num)
    pbar.update()

It also handles multiple progress bars.

import time
import enlighten

manager = enlighten.Manager()
odds = manager.counter(total=50)
evens = manager.counter(total=50)

for num in range(1, 101):
    time.sleep(0.05)
    if num % 2:
        odds.update()
    else:
        evens.update()

The code below is a quite general solution and also has a time elapsed and time remaining estimate. You can use any iterable with it. The progress bar has a fixed size of 25 characters but it can show updates in 1% steps using full, half, and quarter block characters. The output looks like this:

 18% |████▌                    | \ [0:00:01, 0:00:06]

Code with example:

import sys, time
from numpy import linspace

def ProgressBar(iterObj):
  def SecToStr(sec):
    m, s = divmod(sec, 60)
    h, m = divmod(m, 60)
    return u'%d:%02d:%02d'%(h, m, s)
  L = len(iterObj)
  steps = {int(x):y for x,y in zip(linspace(0, L, min(100,L), endpoint=False),
                                   linspace(0, 100, min(100,L), endpoint=False))}
  qSteps = ['', u'\u258E', u'\u258C', u'\u258A'] # quarter and half block chars
  startT = time.time()
  timeStr = '   [0:00:00, -:--:--]'
  activity = [' -',' \\',' |',' /']
  for nn,item in enumerate(iterObj):
    if nn in steps:
      done = u'\u2588'*int(steps[nn]/4.0)+qSteps[int(steps[nn]%4)]
      todo = ' '*(25-len(done))
      barStr = u'%4d%% |%s%s|'%(steps[nn], done, todo)
    if nn>0:
      endT = time.time()
      timeStr = ' [%s, %s]'%(SecToStr(endT-startT),
                             SecToStr((endT-startT)*(L/float(nn)-1)))
    sys.stdout.write('\r'+barStr+activity[nn%4]+timeStr); sys.stdout.flush()
    yield item
  barStr = u'%4d%% |%s|'%(100, u'\u2588'*25)
  timeStr = '   [%s, 0:00:00]\n'%(SecToStr(time.time()-startT))
  sys.stdout.write('\r'+barStr+timeStr); sys.stdout.flush()

# Example
s = ''
for c in ProgressBar(list('Disassemble and reassemble this string')):
  time.sleep(0.2)
  s += c
print(s)

Suggestions for improvements or other comments are appreciated. Cheers!

It is quite straightforward in Python3:

   import time
   import math

    def show_progress_bar(bar_length, completed, total):
        bar_length_unit_value = (total / bar_length)
        completed_bar_part = math.ceil(completed / bar_length_unit_value)
        progress = "*" * completed_bar_part
        remaining = " " * (bar_length - completed_bar_part)
        percent_done = "%.2f" % ((completed / total) * 100)
        print(f'[{progress}{remaining}] {percent_done}%', end='\r')

    bar_length = 30
    total = 100
    for i in range(0, total + 1):
        show_progress_bar(bar_length, i, total)
        time.sleep(0.1)

    print('\n')

progress(50)

I like this page.

Starts with simple example and moves onto a multi-threaded version. Works out of the box. No 3rd party packages required.

The code will look something like this:

import time
import sys

def do_task():
    time.sleep(1)

def example_1(n):
    for i in range(n):
        do_task()
        print '\b.',
        sys.stdout.flush()
    print ' Done!'

print 'Starting ',
example_1(10)

Or here is example to use threads in order to run the spinning loading bar while the program is running:

import sys
import time
import threading

class progress_bar_loading(threading.Thread):

    def run(self):
            global stop
            global kill
            print 'Loading....  ',
            sys.stdout.flush()
            i = 0
            while stop != True:
                    if (i%4) == 0: 
                        sys.stdout.write('\b/')
                    elif (i%4) == 1: 
                        sys.stdout.write('\b-')
                    elif (i%4) == 2: 
                        sys.stdout.write('\b\\')
                    elif (i%4) == 3: 
                        sys.stdout.write('\b|')

                    sys.stdout.flush()
                    time.sleep(0.2)
                    i+=1

            if kill == True: 
                print '\b\b\b\b ABORT!',
            else: 
                print '\b\b done!',


kill = False      
stop = False
p = progress_bar_loading()
p.start()

try:
    #anything you want to run. 
    time.sleep(1)
    stop = True

I used format() method to make a load bar. Here is my solution:

import time

loadbarwidth = 23

for i in range(1, loadbarwidth + 1):
    time.sleep(0.1) 

    strbarwidth = '[{}{}] - {}\r'.format(
        (i * '#'),
        ((loadbarwidth - i) * '-'),
        (('{:0.2f}'.format(((i) * (100/loadbarwidth))) + '%'))
    )

    print(strbarwidth ,end = '')

print()

Output:

[#######################] - 100.00%

Use the progress library!

pip install progress

Here is a custom subclass I wrote to format the ETA/Elapsed times into a better readable format:

import datetime
from progress.bar import IncrementalBar


class ProgressBar(IncrementalBar):
    '''
    My custom progress bar that:
       - Show %, count, elapsed, eta
       - Time is shown in H:M:S format
    '''

    message = 'Progress'
    suffix  = '%(percent).1f%% (%(index)d/%(max)d) -- %(elapsed_min)s (eta: %(eta_min)s)'

    def formatTime(self, seconds):
        return str(datetime.timedelta(seconds=seconds))

    @property
    def elapsed_min(self):
        return self.formatTime(self.elapsed)

    @property
    def eta_min(self):
        return self.formatTime(self.eta)

if __name__=='__main__':
    counter = 120
    bar     = ProgressBar('Processing', max=counter)

    for i in range(counter):
        bar.next()
        time.sleep(1)

    bar.finish()

Here's a short solution that builds the loading bar programmatically (you must decide how long you want it).

import time

n = 33  # or however many loading slots you want to have
load = 0.01  # artificial loading time!
loading = '.' * n  # for strings, * is the repeat operator

for i in range(n+1):
    # this loop replaces each dot with a hash!
    print('\r%s Loading at %3d percent!' % (loading, i*100/n), end='')
    loading = loading[:i] + '#' + loading[i+1:]
    time.sleep(load)
    if i==n: print()

If your work can't be broken down into measurable chunks, you could call your function in a new thread and time how long it takes:

import thread
import time
import sys

def work():
    time.sleep( 5 )

def locked_call( func, lock ):
    lock.acquire()
    func()
    lock.release()

lock = thread.allocate_lock()
thread.start_new_thread( locked_call, ( work, lock, ) )

# This part is icky...
while( not lock.locked() ):
    time.sleep( 0.1 )

while( lock.locked() ):
    sys.stdout.write( "*" )
    sys.stdout.flush()
    time.sleep( 1 )
print "\nWork Done"

You can obviously increase the timing precision as required.

I like Gabriel answer, but i changed it to be flexible. You can send bar-length to the function and get your progress bar with any length that you want. And you can't have a progress bar with zero or negative length. Also, you can use this function like Gabriel answer (Look at the Example #2).

import sys
import time

def ProgressBar(Total, Progress, BarLength=20, ProgressIcon="#", BarIcon="-"):
    try:
        # You can't have a progress bar with zero or negative length.
        if BarLength <1:
            BarLength = 20
        # Use status variable for going to the next line after progress completion.
        Status = ""
        # Calcuting progress between 0 and 1 for percentage.
        Progress = float(Progress) / float(Total)
        # Doing this conditions at final progressing.
        if Progress >= 1.:
            Progress = 1
            Status = "\r\n"    # Going to the next line
        # Calculating how many places should be filled
        Block = int(round(BarLength * Progress))
        # Show this
        Bar = "[{}] {:.0f}% {}".format(ProgressIcon * Block + BarIcon * (BarLength - Block), round(Progress * 100, 0), Status)
        return Bar
    except:
        return "ERROR"

def ShowBar(Bar):
    sys.stdout.write(Bar)
    sys.stdout.flush()

if __name__ == '__main__':
    print("This is a simple progress bar.\n")

    # Example #1:
    print('Example #1')
    Runs = 10
    for i in range(Runs + 1):
        progressBar = "\rProgress: " + ProgressBar(10, i, Runs)
        ShowBar(progressBar)
        time.sleep(1)

    # Example #2:
    print('\nExample #2')
    Runs = 10
    for i in range(Runs + 1):
        progressBar = "\rProgress: " + ProgressBar(10, i, 20, '|', '.')
        ShowBar(progressBar)
        time.sleep(1)

    print('\nDone.')

# Example #2:
Runs = 10
for i in range(Runs + 1):
    ProgressBar(10, i)
    time.sleep(1)

Result:

This is a simple progress bar.

Example #1

Progress: [###-------] 30%

Example #2

Progress: [||||||||||||........] 60%

Done.

Try PyProg. PyProg is an open-source library for Python to create super customizable progress indicators & bars.

It is currently at version 1.0.2; it is hosted on Github and available on PyPI (Links down below). It is compatible with Python 3 & 2 and it can also be used with Qt Console.

It is really easy to use. The following code:

import pyprog
from time import sleep

# Create Object
prog = pyprog.ProgressBar(" ", "", 34)
# Update Progress Bar
prog.update()

for i in range(34):
    # Do something
    sleep(0.1)
    # Set current status
    prog.set_stat(i + 1)
    # Update Progress Bar again
    prog.update()

# Make the Progress Bar final
prog.end()

will produce:

Initial State:
Progress: 0% --------------------------------------------------

When half done:
Progress: 50% #########################-------------------------

Final State:
Progress: 100% ##################################################

I actually made PyProg because I needed a simple but super customizable progress bar library. You can easily install it with: pip install pyprog.

Guess i'm a little late but this should work for people working with the current versions of python 3, since this uses "f-strings", as introduced in Python 3.6 PEP 498:

Code

from numpy import interp

class Progress:
    def __init__(self, value, end, title='Downloading',buffer=20):
        self.title = title
        #when calling in a for loop it doesn't include the last number
        self.end = end -1
        self.buffer = buffer
        self.value = value
        self.progress()

    def progress(self):
        maped = int(interp(self.value, [0, self.end], [0, self.buffer]))
        print(f'{self.title}: [{"#"*maped}{"-"*(self.buffer - maped)}]{self.value}/{self.end} {((self.value/self.end)*100):.2f}%', end='\r')

Example

#some loop that does perfroms a task
for x in range(21)  #set to 21 to include until 20
    Progress(x, 21)

Output

This is my simple solution:

import time

def progress(_cur, _max):
    p = round(100*_cur/_max)
    b = f"Progress: {p}% - ["+"."*int(p/5)+" "*(20-int(p/5))+"]"
    print(b, end="\r")

# USAGE:
for i in range(0,101):
    time.sleep(0.1) 
    progress(i,100)

print("..."*5, end="\r")
print("Done")

A very simple approach:

def progbar(count: int) -> None:
    for i in range(count):
        print(f"[{i*'#'}{(count-1-i)*' '}] - {i+1}/{count}", end="\r")
        yield i
    print('\n')

And the usage:

from time import sleep

for i in progbar(10):
    sleep(0.2) #whatever task you need to do
