I want input data in python but while inputting data,on the right side must be output for example, kilogram:
simple code:
weight = float(input('Enter your weight: (kg)'))
Output:
Enter your weight: some_number (kg)
I want that kg stands always on right side of number while inputting data. I think question is clear if something not please let me know.Thank you in advance!
If you dig around, you'll find various versions of something called getch. This uses code from py-getch:
import sys
try:
from msvcrt import getch
except ImportError:
def getch():
import tty
import termios
fd = sys.stdin.fileno()
old = termios.tcgetattr(fd)
try:
tty.setraw(fd)
return sys.stdin.read(1)
finally:
termios.tcsetattr(fd, termios.TCSADRAIN, old)
ascii_numbers = [ord('0') + x for x in range(10)]
weight = 0.0
while True:
message = f"Enter your weight: {weight:9.2f} (kg)"
sys.stdout.write("\r" + message)
sys.stdout.flush()
c = ord(getch())
if c == 13:
break
elif c in ascii_numbers:
c = c - ord('0')
weight = (weight * 10) + (float(c) / 100)
elif c == 127:
weight = weight / 10
print("")
This is ugly, but my last experience with ncurses was even uglier.
Warning
This program ignores Ctrl-C inside the getch call. It is possible to modify this code so that the only way to stop the program is to kill the process. Sorry.
print("aaaaaaaaaaaaaa\r\tbb")-\ris \carriage return\ which gets you back to the beginning(!) of the current line,\tis a tab character.weight = float(input('Enter your weight (kg): '))?(kg)on left before:-Enter your weight (kg): some_number.
