What are the best practices for using callbacks in Python?

When using callbacks in Python, it's important to keep them simple and focused. Avoid complex logic in callbacks.

Can you give me an example of a simple callback function?

Sure! Here's a simple example:

def my_callback(result):
    print(f'Result: {result}')

def process_data(data, callback):
    result = data * 2
    callback(result)

process_data(5, my_callback)

What should I avoid when implementing callbacks?

Avoid using global variables in callbacks, as they can lead to unexpected behavior. Also, keep callbacks non-blocking.

How can I handle errors in callback functions?

You can handle errors by wrapping the callback call in a try-except block. This way, you can manage exceptions gracefully.
