Debugging Asynchronous Applications in Python

Challenges in debugging asynchronous Python code include unpredictable coroutine execution, race conditions when modifying shared resources, and less informative stack traces. Using logging, asyncio’s debug mode, and careful error handling improves tracing and managing asynchronous errors effectively.

Using pandas.DataFrame.copy to Create Data Copies

Optimizing pandas data manipulation involves minimizing unnecessary copying by using views or shallow copies and modifying data in place with boolean indexing. Avoid chained assignments, specify deep or shallow copies explicitly, and leverage chunked processing for large datasets to improve performance and reduce memory usage.
