# 返回所有的section

#可以按照类型读取出来

#修改一个值，再写回去   
cf.set("db", "db_pass", "zhaowei")   
cf.write(open("test.conf", "w"))  
 
#添加一个section。（同样要写回） 
cf.add_section('liuqing') 
cf.set('liuqing', 'int', '15') 
cf.set('liuqing', 'bool', 'true') 
cf.set('liuqing', 'float', '3.1415')

cf.set('liuqing', 'bar', 'Python') 
cf.set('liuqing', 'foo', '%(bar)s is %(baz)s!') 
cf.write(open("test.conf", "w")) 
 
#移除section 或者option 。（只要进行了修改就要写回的哦） 
cf.remove_option('liuqing','int') 
cf.remove_section('liuqing') 
cf.write(open("test.conf", "w"))
