How do I make python to wait for a pressed key

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 python press any key to continue, 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.
