Delete words made with print()

I want to make code so that a number goes from 1 to 2 to 3 and so on.

I am running this on Python 3. I have tried:

import time
from sys import stdout
for i in range(1,20):
    stdout.write("\r%d" % i)
    stdout.flush()
    time.sleep(1)
stdout.write("\n") # move the cursor to the next line

But with that code, I get 12345678910111213141516171819. Can someone help? EDIT: I ran this code from the console, not from IDLE and it works. Can anyone explain?

For my setup it works (Arch Linux, Python3). Do you start from IDE? Or from console?

Maybe another way works for you:

import time
from sys import stdout
for i in range(1,20):
    print(i)
    time.sleep(0.1)
    stdout.write("\033[F") #back to previous line
    stdout.write("\033[K") #clear line
stdout.write("\n") # move the cursor to the next line

Idea found here. This example works in my console but not when I start from PyCharm directly.
