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()
