What are nested functions in Python?

Nested functions are functions defined inside other functions. They can access variables from the enclosing function.

Can you give me an example of a nested function?

Sure! Here's a simple example:

def outer_function():
    def inner_function():
        return "Hello from the inner function!"
    return inner_function()

print(outer_function())

What are the benefits of using nested functions?

Nested functions can help in organizing code, encapsulating functionality, and avoiding variable name conflicts.

Are there any limitations to using nested functions?

Yes, nested functions can make code harder to read if overused, and they can only be called within the enclosing function.
