Sure! You can use contextlib to create a context manager for file operations, ensuring files are properly closed after use.

Does using contextlib affect performance significantly?

Generally, the performance impact is minimal, but in performance-critical applications, it's worth profiling to ensure it meets your needs.

Are there alternatives to contextlib for context management?

Yes, you can use traditional try-finally blocks or implement your own context manager using the __enter__ and __exit__ methods.
