python中的任意命令行参数 [英] Arbitrary command line arguments in python

问题描述

我想允许使用任意命令行参数。如果用户向我提供了如下所示的命令行

I want to allow arbitrary command line arguments. If the user provides me with a command line that looks like this

myscript.py --a valueofa --b valueofb posarg1 posarg2

我知道 a 是通过 valueofa ， b 与 valueofb 一起传递，并且我有最后两个位置参数。

I know that a was passed with valueofa, b passed with valueofb and that I have these last two positional arguments.

我一直使用optparse，您可以为其精确指定要查找的参数。但是我希望用户能够从命令行定义任意的宏。当然，有一个python模块，它比我写的任何东西都更优雅。什么是？

I've always used optparse, for which you specify exactly which arguments to look for. But I want the user to be able to define arbitrary "macros" from the command line. Surely there's a python module that does it more elegantly than anything I'd write. What is?

推荐答案

可悲的是，您。如果需要支持，则需要编写自己的选项解析器=（。

Sadly, you can't. If you have to support this, you'll need to write your own option parser =(.
