Answer 1

In a nutshell, you need to output \r character, which is a carriage RETURN command. It will put the caret to the start of the line in the console. Next output will basically rewrite the line contents.

import sys, time

i = 0
while True:
    sys.stdout.write('/-\\|'[i%4])
    time.sleep(0.5)
    sys.stdout.write('\r')
    i += 1
