在 Python 中使用设置文件的最佳做法是什么?

问题描述

我有一个带有很多参数的命令行脚本.我现在已经到了一个论点太多的地步，我也想有一些字典形式的论点.

I have a command line script that I run with a lot of arguments. I have now come to a point where I have too many arguments, and I want to have some arguments in dictionary form too.

所以为了简化事情，我想用设置文件来运行脚本.我真的不知道要使用哪些库来解析文件.这样做的最佳做法是什么?我当然可以自己敲出一些东西，但是如果有一些图书馆可以解决这个问题，我会全力以赴.

So in order to simplify things I would like to run the script with a settings file instead. I don't really know what libraries to use for the parsing of the file. What's the best practice for doing this? I could of course hammer something out myself, but if there is some library for this, I'm all ears.

一些要求":

• 而不是使用 pickle，我希望它是一个易于阅读和编辑的简单文本文件.
• 我希望能够在其中添加类似字典的数据，即应该支持某种形式的嵌套.

• Rather than using pickle I would like it to be a straight forward text file that can easily be read and edited.
• I want to be able to add dictionary-like data in it, i.e., some form of nesting should be supported.

一个简化的伪示例文件:

A simplified pseudo example file:

truck: color: blue brand: fordcity: new yorkcabriolet: color: black engine: cylinders: 8 placement: mid doors: 2

推荐答案

你可以有一个普通的 Python 模块，比如 config.py，像这样:

You can have a regular Python module, say config.py, like this:

truck = dict( color = 'blue', brand = 'ford',)city = 'new york'cabriolet = dict( color = 'black', engine = dict( cylinders = 8, placement = 'mid', ), doors = 2,)

并像这样使用它:

import configprint(config.truck['color'])
