Scrolling text, just like the ones you see in train stations :)

scrolling_text.py

from time import sleep

def scrolling_text(text, screen_size, wait):
    text = f"{' '*screen_size}{text}{' '*screen_size}"
    while True:
        for i in range(len(text) - screen_size):
            print('\r', text[i:screen_size+i], end='', sep='', flush=True)
            sleep(wait)


def main():
    text = input("text = ")
    screen_size = int(input("screen size = "))
    wait = float(input("wait = "))
    scrolling_text(text, screen_size, wait)


if __name__ == "__main__":
    main()
