I'm curious about how type hints are viewed in Python compared to TypeScript. Are they common and expected in Python projects, whether for solo work or in team settings? What's your experience with using type hints in your own projects?

I think type hints provide huge advantages, especially with modern IDEs. They reduce guesswork for methods and help clarify your intention. Not using them is like neglecting to document your code – it just makes maintenance harder down the road!
In my workplace, type hints are used religiously for all projects, no matter how small. Once you get used to them, you realize the language feels lacking without them. Using mypy in strict mode has just become the norm for us. It really enhances the coding experience and makes everything clearer!
I've had mixed feelings about mypy. Sometimes it just complicates things for me.
In my opinion, type hints are essential if others will be reading or working on the same code. They really enhance readability and help make the code easier to test and refactor. Even when working solo, if you don't use type hints, you might be limiting yourself. They guide you in writing better code by clearly defining what types you're expecting for function arguments and return values. Once I prioritized type hints, I felt a real shift in my development skills.
Absolutely agree! I also recommend "Robust Python" by Patrick Viafore. It emphasizes the importance of communicating your intent in code, which is crucial in software development.
True, but keep in mind that Python's type hints aren't as robust as TypeScript. You'll still need to navigate some quirks.
In teams I’ve worked with, using mypy for type checking is mandatory. It helps catch issues early and keeps our code quality high.
We follow a similar policy with precommit hooks and strict type checking. It really keeps everyone on the same page.
While I think type hints are valuable, particularly for code maintainability and clarity, they’re not always necessary. For quick scripts or experiments, they might even slow you down. But for a larger project? Definitely a good practice to adopt.
I see your point. Sometimes, it feels like a heavier burden than it's worth for smaller tasks.
Interesting! So you find them helpful even in small scripts?
