What are some examples of using contextlib in Python?

Can you give me some examples of how to use contextlib in Python?

Sure! The contextlib module provides utilities for working with context managers. One common use is contextlib.contextmanager.

How does the contextmanager decorator work?

The contextmanager decorator allows you to define a generator function that can be used with the with statement. You yield the resource and handle setup and teardown.

Can you show me a simple example?

Absolutely! Here's a simple example:

from contextlib import contextmanager

@contextmanager
def my_resource():
    print('Acquiring resource')
    yield 'Resource'
    print('Releasing resource')

with my_resource() as resource:
    print(resource)

What happens if an exception occurs in the with block?

If an exception occurs, the code after the yield statement will still execute, allowing for proper cleanup.
