Can this skill help with Python 3.13's new experimental features?

Yes, it includes specific instructions for enabling, benchmarking, and evaluating the experimental JIT compiler and free-threaded (No-GIL) mode introduced in Python 3.13.

How does it help with memory optimization?

It provides patterns for reducing memory overhead, such as implementing __slots__ for classes with many instances, using generators for lazy data processing, and performing line-by-line memory profiling.

What tools does this skill help me use for profiling?

This skill provides expert guidance on using cProfile for deterministic profiling and py-spy for sampling profiling and generating flame graphs without modifying your source code.

Is this skill suitable for optimizing AsyncIO applications?

Absolutely. It identifies common AsyncIO anti-patterns like event loop blocking and provides high-performance patterns using asyncio.gather and asyncio.to_thread.
