How to Pause Python Script Execution Until User Input?

How to Pause Python Script Execution Until Keyboard Input

If you need your Python script to halt execution until the user presses a key, various approaches are available depending on your Python version and system environment.

Python 3 and Input

In Python 3, you can use the input() function to wait for user input:

input("Press Enter to continue...")

This will display the specified prompt and wait for the user to press the Enter key before proceeding.

Python 2 and Raw Input

In Python 2, the raw_input() function serves the same purpose as input() in Python 3:

raw_input("Press Enter to continue...")

Windows/DOS and Msvcrt

If you're working in a Windows or DOS environment, you can use the msvcrt module to wait for a key press:

import msvcrt as m

def wait():
    m.getch()

This wait() function will pause the script until any key is pressed.

Additional Notes

• In Python 3, raw_input() is not available.
• In Python 2, input(prompt) is equivalent to eval(raw_input(prompt)).
