I am trying to generate a random string of bits using the following code.
bitString = []
for i in range(0, 8):
x = str(random.randint(0, 1))
bitString.append(x)
''.join(bitString)
However instead of giving me something like this:
10011110
I get something that looks like this:
['1','0','0','1','1','1','1','0']
Can anyone point me in the direction of what I'm doing wrong?
Fixing your code:
bitList = []
for i in range(0, 8):
x = str(random.randint(0, 1))
bitList.append(x)
bitString = ''.join(bitList)
But more Pythonic would be this:
>>> from random import choice
>>> ''.join(choice('01') for _ in range(10))
'0011010100'
You are joining the results in the loop itself. You can unindent the join line, like this
import random
bitString = []
for i in range(0, 8):
x = str(random.randint(0, 1))
bitString.append(x)
print ''.join(bitString)
Or, better, you can use generator expression like this
print "".join(str(random.randint(0, 1)) for i in range(8))
You could declare bitString as string variable (instead of appending to list and then converting to string):
bitString = ""
for i in range(0, 8):
x = str(random.randint(0, 1))
bitString += x
print bitString
Your code is right, but misses 3 "words": import, random and print)
import random
bitString = []
for i in range(0, 8):
x = str(random.randint(0, 1))
bitString.append(x)
print ''.join(bitString)
My one-liner would be:
>>> import random
>>> print ''.join(random.choice("01") for i in range(8))
11100000
>>>
