Back on #Python after a couple of years (for data processing, not developing) and I don't even remember how to look inside a dataframe. Why do I do this to myself?

@RomanOnARiver Two very useful features indeed! (IMO)
Personally I'd add type hints in to that list, if you're not already using them

I did not make any good progress on my project to read GPX data with Python today. (Trying to read speed.) May need to just read it as XML.
There are a bunch of nerds who do Python and bikes though, so someone might have the code example I need.

I've coded-up a really cool #Python class: https://pypi.org/project/chord-progression-network/ - It is a network transition, musical chord progression generator. Like a Markov chain thing. :)
Dig it!

Two things I think I need to start using in #python are f-strings and lambdas. It's hard to change though, but when I'm refactoring I'll make an effort. #programming #coding

Sometimes you want to keep #coding and pushing but it's important to take time to rest, it's important to take time to learn and plan. For example I'm dealing with #GTFS-RT data, which I have never used before. It's not just CSVs like #GTFS data is, so I took the time today to better learn the spec and the #python module to interact with it. By the end I was able to take VehiclePositions.pb and convert it to a json file.

It's frustrating as there're a lot of really nice TUI apps written in #python but I often give up during install as life's too short to deal with that mess of an ecosystem.

When a function is defined within a function and the inner function accesses variables from the outer function, Python uses a "closure" to keep track of those variables that are defined just outside the inner function, in its enclosing scope. https://trey.io/4u4pj0

Напердолил целую игру
Уууу, давно хотелось чего-то простого, смешного и без лишних заморочек. Чтобы мемов побольше и можно было с пацанами погонять. В итоге получились "TANKOLINI NAPIERDOLKI" . Старый добрый монохромный экран, тетрис, мультиплеер и редактор карт для каждого. С другой стороны — всё на канвасе, с вручную отрисованными пикселями, без всяких ассетов и движков. Python на бэке, PostgreSQL для карт и Redis для игровых комнат. Обо всём этом — в статье.
