How do context managers work in Python?

Can you explain how context managers work in Python?

Sure! Context managers in Python are used to manage resources, ensuring they are properly acquired and released.

How do I create a custom context manager?

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

Can you give me an example of a context manager?

Absolutely! Here's a simple example using a file context manager:

with open('file.txt', 'r') as file:
    data = file.read()

What happens if an exception occurs inside a context manager?

If an exception occurs, the __exit__ method is called, allowing you to handle the exception or clean up resources.
