What are some examples of using the contextlib module in Python?

Can you give me some examples of how to use the contextlib module 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 would I create a simple context manager using contextlib?

You can define a generator function and use the @contextmanager decorator. For example:

from contextlib import contextmanager

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

Can you show me how to use this context manager?

Absolutely! You can use it like this:

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

This will print 'Entering the context', then 'Inside the context', and finally 'Exiting the context'.
