What is the purpose of the 'with' statement in Python?

The 'with' statement in Python is used for resource management, ensuring that resources are properly managed and released.

Can you give me an example of how to use it?

Sure! Here's a simple example:

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

This automatically closes the file after the block is executed.

What happens if an error occurs inside the 'with' block?

If an error occurs, the 'with' statement still ensures that the resource is properly cleaned up, like closing the file.

Are there other contexts where 'with' can be used?

Yes, 'with' can be used with any object that implements the context management protocol, like database connections or threading locks.
