How do closures affect performance in Python?

Closures can impact performance by creating additional function objects and maintaining state, which may increase memory usage.

Can you give an example of a closure in Python?

Sure! Here's a simple example:

def outer_function(x):
    def inner_function(y):
        return x + y
    return inner_function

closure = outer_function(10)
print(closure(5))  # Outputs: 15

Are there any performance drawbacks to using closures?

Yes, while closures are powerful, they can lead to higher memory consumption and slower execution if overused, especially in tight loops.

When should I avoid using closures?

You might want to avoid closures in performance-critical sections of code or when simpler alternatives, like regular functions, suffice.
