In this tutorial, you'll learn how to use global variables in Python functions using the global keyword or the built-in globals() function. You'll also learn a few strategies to avoid relying on global variables because they can lead to code that's difficult to understand, debug, and maintain.
Variables that are created outside of a function (as in all of the examples in the previous pages) are known as global variables. Global variables can be used by everyone, both inside of functions and outside. Create a variable outside of a function, and use it inside the function.

7 mar 2024 · This article outlines several methods for declaring global variables in Python, ensuring that variables modified within functions reflect the changes globally. We’ll tackle scenarios with initialization on script startup and subsequent modification throughout the program’s execution.
