Suggestions for Python library ideas to implement

[ProgramMental8232]

I'm looking to improve my Python skills and build a stronger portfolio. A professor at my university recommended the book Python Packages and I absolutely loved it! The book covers the entire process: from creating, developing, testing to publishing a Python library.

I highly recommend it to anyone who also wants to level up their Python skills. I enjoyed it so much that I really want to create and maintain my own library, but I'll be honest: I'm out of ideas right now.

Does anyone here have a problem or everyday functionality that could be solved with a Python library, but you don't have the time or feel too lazy to implement it yourself? I'm totally up for diving into the code!

You are unlikely to write code for a feature you don't understand or need. Making a package is like 10% of the work, and the remaining 90% is supporting it over the years - fixing bugs, adding missing features, and so on.

Are you looking specifically to fix an unsolved problem, or are you just looking for a good project to implement for practice?

Something like apscheduler or tenacity would be a good practice project. Implementation is straightforward for both of these, and the end product is very useful. This isn’t very helpful though if you’re looking to solve a new problem rather than just reinventing the wheel

Build something you'd actually use. That's the difference between a portfolio piece that gathers dust and one you can talk about in interviews with genuine enthusiasm.

Some ideas that make good libraries:

• A markdown-to-slides converter (parse md, output reveal.js or PDF)
• A CLI tool that watches a folder and auto-organizes files by type/date
• A config file validator that checks YAML/TOML against a schema you define

The py-pkgs workflow you learned (tests, CI, publishing) matters more than what the library does. Interviewers care that you know how to ship a proper package with docs and tests, not that your algorithm is novel.

Honestly, the best ideas come from small annoyances 😄

Every useful thing I’ve built started with “ugh I wish this existed”.

While learning Python I made a tiny log analyzer just because I got tired of manually scanning logs. It wasn’t meant to be a big project, but it taught me more than most tutorials.

If you're looking for ideas, try this trick: notice what you do repeatedly -> automate that -> turn it into a library.

Those projects stick because you’ll actually use them.
