[issue45275] Make argparse print description of subcommand when invoke help doc on subcommand
New submission from Chuanlong Du : I have command-line script `blog` written using argparse. It supports subcommands. When I check the help doc of a subcommand, e.g., using `blog convert -h`, it prints the help doc of the subcommand `blog convert` but doesn't print the description of the subcommand `blog convert`. A screenshot is attached. It is quite often that I know a command-line application have certain subcommands but I forget exactly what they do. It would be very helpful if `blog subcmd -h` prints the description of the subcmd so that users do not have to call `blog -h` again to check exactly what the subcommand does. -- components: Library (Lib) files: Selection_011.png messages: 402541 nosy: longendu priority: normal severity: normal status: open title: Make argparse print description of subcommand when invoke help doc on subcommand type: enhancement versions: Python 3.10, Python 3.11, Python 3.6, Python 3.7, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file50301/Selection_011.png ___ Python tracker <https://bugs.python.org/issue45275> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ningyi Du added the comment: I believe it's a bug. The axis 0 is misleading. However, it is a problem for numpy developers. Thank you for your time.

[issue33129] Add kwarg-only option to dataclass
New submission from Alan Du : I'd like to request a new option to the `dataclasses.dataclass` decorator to make the `__init__` keyword-only. The two use-cases I have in mind are: (1) Using as a dataclass big-bag-of-config. In this scenario, forcing the user to specify the keywords is a lot nicer than passing in a dozen positional parameters. (2) Having kwarg-only parameters means that inheritance and default parameters play nicely with each other again instead of raising a TypeError. -- components: Library (Lib) messages: 314341 nosy: alan_du, eric.smith priority: normal severity: normal status: open title: Add kwarg-only option to dataclass type: enhancement versions: Python 3.7, Python 3.8 ___ Python tracker <https://bugs.python.org/issue33129> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Alan Du added the comment: If this would be accepted, I'd be happy to contribute a patch adding a `kwarg_only` option to `dataclass` (although it might take me a while since I'm not super familiar with the Python development workflow).

[issue6570] Documentation Clarity
New submission from Mark du Preez : Hi In section 4.7.2 of the tutorial documentation, we suddenly find the following paragraph: "In general, an argument list must have any positional arguments followed by any keyword arguments, where the keywords must be chosen from the formal parameter names. It’s not important whether a formal parameter has a default value or not. No argument may receive a value more than once — formal parameter names corresponding to positional arguments cannot be used as keywords in the same calls. Here’s an example that fails due to this restriction:" To a beginner who is reading a tutorial to learn how to use this language for the first time, it is completely overwhelming. What is a "positional argument" vs a "keyword argument" and what is a "formal parameter name"? None of these things have been explained up until this point and an understanding of their meaning is required to make sense of this paragraph. Please consider revising this section. Thank you.
