If you are using Python 3 version then you can use the following syntax to make a wait key:-
input("Press Enter to continue...")
If you are using Python 2, you should use raw_input(), as input(prompt) is equivalent to eval(raw_input(prompt)):
raw_input("Press Enter to continue...")
All these methods only wait for a user to press the enter button, so you might want to use msvcrt which works in Windows/DOS only. The msvcrt module gives you access to a number of functions in the Microsoft Visual C/C++ Runtime Library (MSVCRT)):
import msvcrt as m
def wait():
m.getch()
So you can use it to make a program for a wait keypress.
