In this video by Programming for beginners we will see Variable Scope in Python Programming for Beginners, in Python tutorial for beginners series.
Python programming language is very easy to learn for students and professionals.
In Python, we can declare variables in three different scopes: local scope, global, and nonlocal scope.
1. Local Variables
When we declare variables inside a function, these variables will have a local scope (within the function). We cannot access them outside the function.
2. Global Variables
A variable declared outside of the function or in global scope is known as a global variable. This means that a global variable can be accessed inside or outside of the function.
3. Nonlocal Variables
nonlocal variables are used in nested functions whose local scope is not defined. This means that the variable can be neither in the local nor the global scope.
