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

The 'with' statement in Python simplifies exception handling by encapsulating common preparation and cleanup tasks. It ensures that resources are properly managed, like closing files automatically.

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 reading, even if an error occurs.

Are there any performance benefits?

Yes, using 'with' can improve performance by reducing the amount of code needed for resource management, making your code cleaner and easier to read.

What types of resources can I manage with 'with'?

You can manage files, network connections, database connections, and any object that implements the context management protocol (i.e., has enter and exit methods).
