What are the benefits of using a with statement in Python?

The with statement simplifies exception handling by encapsulating common preparation and cleanup tasks. It ensures that resources are properly managed.

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

Sure! For example, when working with files, you can use it like this:

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

This automatically closes the file after the block is executed.

Are there any performance benefits?

Yes, using a with statement can improve performance by reducing the amount of code needed for resource management, making your code cleaner and potentially faster.

What types of resources can I manage with it?

You can manage files, network connections, database connections, and any object that implements the context management protocol (with __enter__ and __exit__ methods).
