What are some common mistakes made by context managers in Python?

Some common mistakes include not properly handling exceptions, failing to release resources, and nesting context managers incorrectly.

Can you give an example of a mistake with exception handling?

Sure! A common mistake is using a context manager without a try-except block, which can lead to resource leaks if an exception occurs.

What about nesting context managers? How can that go wrong?

Nesting context managers can lead to confusion if not done carefully. For example, if the inner context manager fails, the outer one may not release resources properly.

How can I avoid these mistakes?

To avoid these mistakes, always use try-except blocks, ensure proper resource management, and test nested context managers thoroughly.
