What are closures in Python?

Can you explain what closures are in Python?

Sure! A closure in Python is a function that remembers its enclosing lexical scope even when the function is executed outside that scope.

Can you give me an example of a closure?

Absolutely! 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 practical uses of closures?

Closures are useful for data hiding and encapsulation, allowing you to create functions with private variables.

Are there any limitations to using closures?

Yes, closures can lead to memory leaks if not handled properly, as they keep references to their enclosing scope.
