Better to overwrite the whole line otherwise the new line will mix with the old ones if the new line is shorter.

import time, os
for s in ['overwrite!', 'the!', 'whole!', 'line!']:
    print(s.ljust(os.get_terminal_size().columns - 1), end="\r")
    time.sleep(1)

Had to use columns - 1 on Windows.
