Impara Nested Functions in Python: Scope and Accessibility | Understanding Variable Scope in Python
Intermediate Python Techniques

bookNested Functions in Python: Scope and Accessibility

This topic will not only help understand the nonlocal scope but also closures and decorators.

Functions are first-class citizens in Python. They can be:

  • Passed as arguments to functions;
  • Returned from functions;
  • Modified;
  • Assigned to variables.

Let's explore some examples:

def outer_function(...):
	...
    def inner_function(...):
		...
	return ...

In programming, a nested function is a function that is defined inside another function.

123456
def count_percent(num1, num2, num3): def inner(num): return num * 30 / 100 return (inner(num1), inner(num2), inner(num3)) print(count_percent(700, 300, 1000))
copy

Useful if you want to perform a complex task multiple times within another function without repeating code.

Tutto è chiaro?
