How to show percentage along with progress bar in python?

Question

In python I can show a progress bar:

import time 
print("0%\u2502{:>21s}0%".format("\u2502"), end='')
print("\b"*23,end='')
for _ in range(20):
    print("\u2588", end='')
    time.sleep(.05)

I would like to also show the percentage. How can I do that?

Answer 1

Use sys.stdout.write() and \r to print a new string with the percentage and progress bar over the previous line each time.

import time
import sys

for x in range(21):
    sys.stdout.write("\r{:>3}%\u2502{:<20}\u2502".format(x * 5, "\u2588" * x))
    time.sleep(.05)
