如何在组中显示 argparse 子命令? [英] how to show argparse subcommands in groups?

问题描述

对于具有许多子命令的程序，我想在 --help 输出中按逻辑分组显示它们.Python argparse 有一个 add_argument_group 方法，但它似乎与子解析器不兼容.子解析器只能添加到顶级ArgumentParser，并且_SubParsersAction 不允许参数组.有没有办法解决这个问题?

For a program with many subcommands, I'd like to show them logically grouped in the --help output. Python argparse has a add_argument_group method, but it doesn't seem compatible with subparsers. subparsers can only be added to the top level ArgumentParser, and _SubParsersAction doesn't allow argument groups. Is there some way around this?

推荐答案

除了实现自定义 HelpFormatter 之外，您无法真正以任何直截了当的方式做到这一点.

You can't really do it in any straightforward way, other than implementing a custom HelpFormatter.

您可以在 文档的这一部分.

You can find some more information on HelpFormatter flavors in this part of the documentation.
