What are closures in Python?

Closures in Python are functions that remember their enclosing lexical scope even when the function is executed outside that scope.

Can you give me an example of a closure?

Sure! Here's a simple example:

def outer_function(msg):
    def inner_function():
        print(msg)
    return inner_function

closure = outer_function('Hello, World!')
closure()  # This will print 'Hello, World!'

What are the benefits of using closures?

Closures help in data hiding and encapsulation, allowing you to create functions with private variables.

Are there any drawbacks to using closures?

Yes, closures can lead to increased memory usage and can make debugging more complex due to their nested nature.
