You can define a Python nested function, just initialize another function within a function by using the
def keyword. Let’s start with a code example containing a nested function:
def outer_func(): def inner_func(): print("Hello, World!") inner_func() outer_func()
Output: Hello, World!
Nested functions are used for encapsulation and closures/factory functions.

Simple example code.
def greeting(first, last): # nested helper function def f_name(): return first + " " + last print("Hi, " + f_name() + "!") greeting('John', 'King')
