I love using the project that I've been working on actually lately as we've been adding a lot of type annotations internally. That's, you know, Python 3 feature right there. And then notable pipe, your IP package, give a shout out to Python modernize and pre commit. One of my favorite packages, we have like an internal package that has a lot of the like functions that are in more tools,. But they're worse, or like, cookie in some way that I don't like.
