What are custom context managers in Python?

Custom context managers in Python allow you to define your own behavior for the with statement, managing resources efficiently.

Can you give me an example of how to create one?

Sure! You can create a custom context manager by defining a class with __enter__ and __exit__ methods.

What does the __enter__ method do?

The __enter__ method is executed when the execution flow enters the context of the with statement, allowing you to set up resources.

And what about the __exit__ method?

The __exit__ method is called when the execution flow leaves the context, allowing you to clean up resources.
