How can I create custom context managers in Python using contextlib?

You can create custom context managers in Python using the contextlib module. Would you like a simple example?

Yes, please provide an example.

Here's a basic example:

from contextlib import contextmanager

@contextmanager
def my_custom_manager():
    print('Entering the context')
    yield
    print('Exiting the context')

with my_custom_manager():
    print('Inside the context')

This will print messages when entering and exiting the context.

What does the yield statement do in this context?

The yield statement allows you to define a point where the context is active. Code before yield runs when entering the context, and code after runs when exiting.
