Trying to implement a python spinner but this code doesnt print anything till it finishes

Question

from time import sleep

for _ in range(10):
    for i in '|/-\\':
        print(i, end='')
        sleep(2)
        print('\b', end='')

Shouldn't this print a character then wait for 2 seconds and then delete it and start again?

For me this code runs with a blank line and only gives an output when its finished or stopped in middle. I've tried it on cmd and powershell

print output normally buffers internally. you will probably have to redirect directly to stdout to get the data to flush after every write. — RufusVS, May 17 '21 at 13:14
you can try also passing the keyword argument `flush=True` to print as you do with `end=''` — Chris Doyle, May 17 '21 at 13:22

Try this:

from time import sleep
import sys

for _ in range(10):
    for i in '|/-\\':
        sys.stdout.write(i)
        sleep(2)
        print('\b', end='')

Use print(i, end='\r') and remove print('\b', end='')
