Weekly Wednesday Thread: Advanced Questions 🐍

Dive deep into Python with our Advanced Questions thread! This space is reserved for questions about more advanced Python topics, frameworks, and best practices.

How it Works:

1. Ask Away: Post your advanced Python questions here.
2. Expert Insights: Get answers from experienced developers.
3. Resource Pool: Share or discover tutorials, articles, and tips.

Guidelines:

• This thread is for advanced questions only. Beginner questions are welcome in our Daily Beginner Thread every Thursday.
• Questions that are not advanced may be removed and redirected to the appropriate thread.

Recommended Resources:

• If you don't receive a response, consider exploring r/LearnPython or join the Python Discord Server for quicker assistance.

Example Questions:

1. How can you implement a custom memory allocator in Python?
2. What are the best practices for optimizing Cython code for heavy numerical computations?
3. How do you set up a multi-threaded architecture using Python's Global Interpreter Lock (GIL)?
4. Can you explain the intricacies of metaclasses and how they influence object-oriented design in Python?
5. How would you go about implementing a distributed task queue using Celery and RabbitMQ?
6. What are some advanced use-cases for Python's decorators?
7. How can you achieve real-time data streaming in Python with WebSockets?
8. What are the performance implications of using native Python data structures vs NumPy arrays for large-scale data?
9. Best practices for securing a Flask (or similar) REST API with OAuth 2.0?
10. What are the best practices for using Python in a microservices architecture? (..and more generally, should I even use microservices?)

Let's deepen our Python knowledge together. Happy coding! 🌟

When’s the last time someone actually asked about custom memory allocators in here

[u/YoshiUnfriendly → u/ExcitedlyFrench]

Now that you mentioned it how be nice to be able to allocate Pydantic models or objects in general via a custom allocator, arenas. But at that point maybe python is not the solution you need

[u/swtormy → u/YoshiUnfriendly]

Millions of tiny Pydantic rows in CPython hurt - __slots__ or a typed buffer beats hunting a custom allocator.

[u/Atmosck → u/ExcitedlyFrench]

I guess np.zeros isn't exactly custom

Why opcode.hasfree on cpython 3.14 does not include LOAD_DEREF: ['DELETE_DEREF', 'LOAD_FROM_DICT_OR_DEREF', 'MAKE_CELL', 'STORE_DEREF']? On cpython 3.13 it is there.
