Python Hub Weekly Digest for 2025-07-20
This week in Python, a popular video demonstrated how to use abstractions to avoid spaghetti code in Python projects. The throttled-py library was introduced, offering Python rate limiting with multiple algorithms and storage backends. An article discussed the benefits of deploying Django projects with Coolify, while another explored how type annotations are transforming Python. The desto tool was highlighted, which allows you to manage your bash and Python scripts through a web dashboard. Other notable topics included the optimization of LLM workflows, Python performance tricks, and the scaling of recommendation services at OLX. Have a great week and happy coding!

How I Use Abstraction to Avoid Spaghetti Code
The video explains why Python projects often devolve into "spaghetti code" and shows how using abstractions such as Callable, Abstract Base Classes (ABC), and Protocol can make codebases more modular, testable, and maintainable. Through a step-by-step refactoring of an image processing example, it highlights how applying the right abstractions early reduces coupling and import complexity...
throttled-py: Python rate limiting library with multiple algorithms (Fixed Window, Sliding Window, Token Bucket, Leaky Bucket & GCRA) and storage backends (Redis, In-Memory).
It is available in both synchronous and asynchronous modes, supports waiting and retrying mode, provides access methods such as function call / function calls/decorators/context managers.
Hosting your Django sites with Coolify
The article explains how deploying Django projects with Coolify streamlines the process by containerizing the app with Docker, automating builds, and managing environment variables through Coolify’s UI. This approach enables easier, near zero-downtime deployments compared to manual server setups, though users should note some nuances with environment variable availability during build steps.
Types are Transforming Python
The article describes how type annotations and new typing features have transformed Python, making code more robust, maintainable, and easier to understand by enabling static analysis, better tooling, and safer refactoring. Modern additions like data classes, generics, protocols, and TypedDict have improved both developer experience and runtime capabilities, allowing Python to compete mo...
desto
desto lets you run and manage your bash and Python scripts in the background (inside tmux sessions) through a simple web dashboard. Launch scripts, monitor their and your system's status, view live logs, and control sessions—all from your browser.
