What are some examples of callbacks in Python libraries?

Callbacks are functions that are passed as arguments to other functions. In Python, libraries like Flask and asyncio use callbacks extensively.

Can you give me a specific example from Flask?

Sure! In Flask, you can use the @app.route decorator to define a callback function that handles requests to a specific URL.

What about an example in asyncio?

In asyncio, you can use the loop.call_soon() method to schedule a callback function to be called soon after the event loop is running.

Are there any other libraries that use callbacks?

Yes, libraries like Twisted and PyQt also utilize callbacks for handling events and asynchronous operations.
