On the spot counter

I would like to display a count in the Console such that each increment is replaced in the same place (at start of line) by the next.
Having looked at posts on overwriting the last line, I thought this should work ok, but it adds each increment to the last line instead of replacing it

Python Code:
import time
for i in range (15):
print(i, end=“\r”)

result is:
note also that when it gets to 6 there is a long gap to 7:
123456 7

What am I doing wrong?

Many thanks
