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

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

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()
