🎨 Old news: I added colour to argparse CLI help in last month's Python 3.14.
⭐ New news: I just added colour to ruff and ty's help so they can catch up (uv already had colour).
Pythonを避けてきた理由やNeovimが好きになれない理由も似たような感じです。保守的なもので……
Pythonは2系から3系への破壊的移行は言うに及ばず、最近でもgetoptみたいな基本的な機能でゴタゴタしていたりとか、後方互換性という考えは無いんだろうなと思うとちょっと使いたくない感じです (使いますけど)

Neovimは最近会社のPCで使っていいことになって (気付いたのは10/22ですがいつから使えたのかは不明)、Windows 11 23H2にアップデートしたところEmacsの起動に30分近く掛かるように (原因はWindowd Defenderのせいだろうなと見当はついているのですが管理者権限がないと手出しできないため解決不能) なったこともあり渡りに船と乗り換えたのですが、Vimからの移行を意識していそうな割にはOptionの規定値がVimと違うもの (hlsearchとか) がちらほらあって戸惑っています。
規定値の説明は確かにhelpにはあるけれど、そのことについて事前に知る手段は特にないので使ってみたら予想外の動作をして驚いて調べて比較してようやく気付く、という感じで不親切な印象は拭えず。
Vimだったら規定値は変えずにdafaults.vimで対応するところだよなあと思ったり。後方互換性(ry
So my side side project to print out help for ALL the commands and subcommands and so on for an #Argparse app. Although it will make best efforts for other commands.
`totalhelp pipx` -- seems to work.
`totalhelp llm` -- incredibly slow.
also has library version for
`my_command --totalhelp` and it shows all the help for all the commands.

Had an enjoyable afternoon building a custom #cli #parser to replace #argparse in our internal tooling. I like its ease of use. But it is a custom parser and works only for my specific use case, but for use case it does more than argparse can and is simpler to use. #comandline #python
argparse is maybe-okay for simple things, but I don't use it for pretty much anything anymore. Have you tried one of the other extant packages that provide higher-level, more-powerful option handling?
I use `click` extensively for complex multiple-command CLI tools.
It's probably a case of #bikesheding, but I've been really unhappy with the #python 's #argparse library for a while now. It's okay for run of the mill tools, but fails for more complex command line tools that have subcommands and complex options like --no-except to negate an option.
This is my first cut writing a command line parser for a #cli

Migrated my user-space environement over to #Python 3.14.0b1 today.
Nice to see the majority of the packages I use work without issue, so far.
Plus, I get that all that pretty colored output from #argparse!
How to create flask web app with python

TIL: #Python's #argparse module cannot parse arguments that start with a dash. It always expects them to be a flag and then throws an error if that flag is not defined.
https://github.com/python/cpython/issues/61252
My use case: I have a command with subparsers/subcommands, and I'd like one of these subcommands to just take all of argv that follows its name and pass it on to someplace else.
mycmd subcmd foo -bar --baz
subcmd.add_argument("args", nargs="*") doesn't work.
Guess I'll have to resort to a hack.
🎉 Please welcome @savannah as the newest member of the Python core team!
She has recently been doing lots of excellent work on the new JIT and giving argparse some long-overdue attention.

@mhd I was quite fond of Amiga #CLI syntax, which many did not consider a proper #Amiga subsystem because of #BCPL, but it allowed commands to pre-declare the arguments in a uniform, documented way similar to Python’s #argparse.
It’s actually handled by BCPL’s rdargs() function, documented in https://www.cl.cam.ac.uk/~mr10/bcplman.pdf (p68).

TIL that #python #argparse can't support negative floating numbers as arguments. Like, the bug is closed RESOLVED, even though if you read through the actual resolution is WONTFIX.
They just decided that argparse (in the stdlib!) is too complex to update and we should use a different library. So now I have to port my app and in the meantime "can't resolve ticket, bug is upstream" is not very satisfying.
Validates #rustlang's strategy of keeping std small to avoid exactly this type of issue.
