In this tutorial, i have explained how to access variables outside a function in python In python, variables that are only referenced inside a function are implicitly global I discussed the variable scope, global variables, modify global variables, local variables, and nonlocal variables in python.

This tutorial will guide you through accessing and modifying global variables in python functions using the global keyword and the globals() function
You’ll also learn to manage scope and avoid potential conflicts between local and global variables.
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. In this python article, we will learn about global variables and global keywords in python We will discuss how to change a global variable from a function in python.
If you’ve ever written a python function and encountered an `unboundlocalerror` when trying to modify a variable defined outside the function, you’re not alone This common issue arises from python’s scoping rules, which determine how variables are accessed and modified in different parts of your code Global variables—variables defined outside of any function or class—can be tricky. By default, variables created inside a function are local to that function
To modify or create a global variable inside a function, you can use the global keyword, which allows the function to access and update the global variable.
Learn about the scope of global variables in python and how they can be accessed and modified by any function or module in the program. Learn how to use global variables in python functions, explore best practices, avoid common pitfalls, and discover cleaner alternatives with real code examples.
