How to Call a Function which is Inside a Function in Python

Guide Kit

A unit of code known as a function carries out a particular purpose. Large codebases may be organised and maintained more easily because functions enable code reuse and modularity. Functions are defined using the keyword "def" in Python, followed by the function name and parentheses ( ).

A function that is defined inside another function is called an inner function. Inner functions are also known as nested functions or local functions. They are only accessible within the scope of the outer function in which they are defined and cannot be called outside of that function. Inner functions can access the variables and parameters of the outer function and can also receive their own set of input parameters. In Python, you can call a function inside another function by first defining the inner function, then calling it within the outer function. You can also return the inner function and call it outside the outer function.

You may have a look at the code given below for learning how to call a function which is inside a function in Python.
