Midiscript.org | The core repo is a small Python DSL that turns files into… The core repo is a small Python DSL that turns `.ms` files into MIDI. Under the hood it’s a CLI + lexer + parser + MIDI generator.

Using too much metaprogramming in a dynamically typed language like Python can confuse your IDE and your type checker. On the other side, typing everything by hand can create mistakes. One idea you can try is to write scripts that generate code. That way you won't have to type everything by hand, and still get the benefits of your type checker/IDE.

Still making iterables like this? 🤦 Learn how to make a Python class iterable using the __iter__ dunder method. A simple Python tip to loop through objects directly instead of accessing their internal data. Are you using Python dunder methods in your projects?

🚀 Levelling up Python with match! One of the most exciting additions in Python 3.10 is the match statement — a cleaner, more powerful alternative to long if...elif...else chains. ✨ Why it matters: Simplifies code readability Supports complex patterns (tuples, types, conditions) Uses _ as a wildcard for default cases Brings Python closer to the elegance of switch-case constructs in other languages For anyone working on decision-heavy logic, this is a game-changer. Cleaner code → fewer bugs → faster collaboration. 💡 Curious: Have you started using match in your projects yet? How does it compare to your old conditional workflows? #Python #CodingTips #SoftwareDevelopment #Python310 #CleanCode

Friday brings #Python Today I have something special for you. If you’ve ever used generators in Python, you’re probably familiar with the `yield` keyword. But what about `yield from`? Take a look at the image: it lets the current generator delegate control to another generator until it’s finished.

Recently I released v2 of immobilus — my small Python library for deterministic time control in tests. The project was completely redesigned and now includes: • thread-safe time freezing • a pytest plugin • flexible time control (tick, jumps, shifts) Feel free to check it out: https://lnkd.in/dTN_ksie #python #testing #pytest #opensource
