Something like this, assuming your terminal handles b

import sys
import time

def spinning_cursor():
    while True:
        for cursor in '|/-\':
            yield cursor

spinner = spinning_cursor()
for _ in range(50):
    sys.stdout.write(next(spinner))
    sys.stdout.flush()
    time.sleep(0.1)
    sys.stdout.write('b')
