发现一个简单而又强大的读写配置文件的lib，http://www.voidspace.org.uk/python/configobj.html。
个人觉得最大的亮点在于自带的格式校验功能，并且支持复杂的嵌套格式，而且使用起来也相当的简便。

来看例子吧。
读文件

复制代码 代码如下:

from configobj import ConfigObj
config = ConfigObj(filename)

value1 = config['keyword1']    
value2 = config['keyword2']    
#    
section1 = config['section1']    
value3 = section1['keyword3']    
value4 = section1['keyword4']    
#    
# you could also write    
value3 = config['section1']['keyword3']    
value4 = config['section1']['keyword4']   

写文件

复制代码 代码如下:

from configobj import ConfigObj
config = ConfigObj()
config.filename = filename

config['keyword1'] = value1    
config['keyword2'] = value2    
#    
config['section1'] = {}    
config['section1']['keyword3'] = value3    
config['section1']['keyword4'] = value4    
#    
section2 = {    
    'keyword5': value5,    
    'keyword6': value6,    
    'sub-section': {    
        'keyword7': value7    
        }    
}    
config['section2'] = section2    
#    
config['section3'] = {}    
config['section3']['keyword 8'] = [value8, value9, value10]    
config['section3']['keyword 9'] = [value11, value12, value13]    
#    
config.write()
