[Python] Nonblocking keyboard input in python Idle windows

Hi,
I want to solve the problem like this running on Idle python windows

The problem:
the program continue printing 1,2,3,4,5.... until it receives the
input 'enter' from keyboard then it stops printing

this could be done using msvcrt.kbhit() and msvcrt.getch() on command prompt
windows
However, those methods could not work in Python Idle windows.
Any of you guys know the methods to solve this problem?

Thanks in advance.
