Python 配置解析器找不到部分? [英] Python Config Parser can't find section?

问题描述

我正在尝试使用 ConfigParser 为我的 pygame 游戏读取 .cfg 文件.由于某种原因，我无法让它发挥作用.代码如下所示:

I'm trying to use ConfigParser to read a .cfg file for my pygame game. I can't get it to function for some reason. The code looks like this:

import ConfigParser
def main():
    config = ConfigParser.ConfigParser()
    config.read('options.cfg')
    print config.sections()
    Screen_width = config.getint('graphics','width')
    Screen_height = config.getint('graphics','height')

此文件中的 main 方法在游戏的启动器中调用.我已经测试过了，效果很好.当我运行此代码时，出现此错误:

The main method in this file is called in the launcher for the game. I've tested that out and that works perfectly. When I run this code, I get this error:

Traceback (most recent call last):
  File "Scripts\Launcher.py", line 71, in <module>
    Game.main()
  File "C:\Users\astro_000\Desktop\Mini-Golf\Scripts\Game.py", line 8, in main
    Screen_width = config.getint('graphics','width')
  File "c:\python27\lib\ConfigParser.py", line 359, in getint
    return self._get(section, int, option)
  File "c:\python27\lib\ConfigParser.py", line 356, in _get
    return conv(self.get(section, option))
  File "c:\python27\lib\ConfigParser.py", line 607, in get
    raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'graphics'

问题是，有一个图形"部分.

The thing is, there is a section 'graphics'.

我试图读取的文件如下所示:

The file I'm trying to read from looks like this:

[graphics]
height = 600
width = 800

我已经确认它实际上被称为 options.cfg.config.sections() 只返回这个:"[]"

I have verified that it is, in fact called options.cfg. config.sections() returns only this: "[]"

在使用相同的代码之前我已经完成了这项工作，但现在无法工作.任何帮助将不胜感激.

I've had this work before using this same code, but it wont work now. Any help would be greatly appreciated.

推荐答案

我总是使用 SafeConfigParser:

from ConfigParser import SafeConfigParser

def main():
    parser = SafeConfigParser()
    parser.read('options.cfg')
    print(parser.sections())
    screen_width = parser.getint('graphics','width')
    screen_height = parser.getint('graphics','height')

还要确保有一个名为 options.cfg 的文件，并在需要时指定完整路径，正如我已经评论过的.如果没有找到文件，解析器将静默失败.

Also make sure there is a file called options.cfg and specify the full path if needed, as I already commented. Parser will fail silently if there is no file found.
