Scope of Variable: Python's Variable Potential

Everything has a scope in this world and not all will be useful everywhere. Each has a particular area where it can shine the brightest. This is applicable to humans, animals, and even to coding as well. Feeling confused? Don't worry, what I mean by that is every code has a specific scope that can only work best under certain conditions.

You have learned about variables in Python in the previous article and how much impact it has on Python code. Combining this with the concept that I mentioned above, you are going to learn about the scope of variables in Python in this article. It is very important for you to learn this concept as it can help you decide which variables to use according to the situation to make the code more efficient and visible so without further ado, let's get started.

In Python, the scope of a variable refers to the region of the program where the variable is recognized and can be accessed. The scope determines the visibility and lifetime of a variable within the program.

It is very important to understand the scope of variables in order to write structured and maintainable code. Python offers various scopes for variables that include global, local, enclosing (non-local), and class scopes. Let us learn more about this in the upcoming section.
