In Python, a callback function is a function that you pass as an argument to another function, allowing it to be executed later. Here’s how you can create and use a simple callback function:
Define the callback function: This is the function to be executed later.
Pass the callback as an argument: Provide the callback function to another function.
Call the callback: Invoke the callback function within the other function.
For example, if you have a function that performs a task and then calls another function to handle the result, you can use a callback to define that behavior dynamically. This is commonly used in event-driven programming or asynchronous code.
