What version of windows are you using? Are you running it from the console, or an ide?

I'm on Windows 10, with python 3.7.0, and your code works as expected:

>>> import time
>>> for n in range(5):
...   print(f"time is {n}", end="\r")
...   time.sleep(0.1)
... else:
...   print()
...
time is 4
>>>
