What is context manager nesting in Python?

Can you explain what context manager nesting is in Python?

Sure! Context manager nesting refers to using multiple context managers within a single 'with' statement.

Why would I want to use nested context managers?

Nesting context managers can help manage resources more efficiently, ensuring that all resources are properly handled.

Can you give me an example of nested context managers?

Absolutely! Here's a simple example:

with open('file1.txt') as f1, open('file2.txt') as f2:
    data1 = f1.read()
    data2 = f2.read()

This opens both files and ensures they are closed after the block.

Are there any potential issues with nesting context managers?

Yes, if not managed properly, it can lead to complex code and make error handling more difficult. It's important to keep it readable.
