Can you give me some examples of using contextlib in Python?

Sure! The contextlib module provides utilities for working with context managers. One common example is using contextlib.contextmanager to create a custom context manager.

How do I create a simple context manager using contextlib?

You can create a simple context manager like this:

from contextlib import contextmanager

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

You can use it with a with statement.

What happens when I use the with statement with this context manager?

When you use the with statement, it will execute the code before the yield when entering the context and the code after the yield when exiting the context.

Can you show me how to use it in a program?

Absolutely! Here's how you can use it:

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

This will output:

Entering the context
Inside the context
Exiting the context
