You do not need the flush parameter.

It works for me.

In [1]: for i in range(10): # stupid mistake :D
   ...:     print("i", end='\r')
   ...:     
i
In [2]: for i in range(10):
   ...:     print(i, end='\r')
   ...:     
9
In [3]: from time import sleep

In [4]: for i in range(10):
   ...:     print(i, end='\r')
   ...:     sleep(0.5)
   ...:     
9
In [5]: from time import ctime

In [6]: for i in range(10):
   ...:     print(ctime(), end='\r')
   ...:     sleep(0.5)
   ...:
