When should I use the with statement in Python?

When should I use the with statement in Python?

The with statement is used for resource management, like file handling, to ensure proper acquisition and release.

Can you give me an example of using the with statement?

Sure! Here's a simple example:

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

This automatically closes the file after the block.

What happens if I don't use the with statement?

If you don't use it, you need to manually close the file, which can lead to resource leaks if you forget.

Are there other contexts where the with statement is useful?

Yes, it's also useful with database connections, threading locks, and any context that requires setup and teardown.
