How do I use callback functions in Python?

Callback functions in Python are functions that are passed as arguments to other functions. They are executed after a certain event or condition is met.

Can you give me an example of a callback function?

Sure! Here's a simple example:

def greet(name):
    return f'Hello, {name}!'

def process_name(callback, name):
    return callback(name)

result = process_name(greet, 'Alice')
print(result)  # Output: Hello, Alice!`

What are some common use cases for callback functions?

Common use cases include handling asynchronous operations, event handling in GUIs, and implementing custom behavior in libraries.

Are there any drawbacks to using callback functions?

Yes, they can lead to callback hell if not managed properly, making code harder to read and maintain.
