python读写config文件

在python中，可以使用configparser这个包来读写。

db.conf文件


[mysql]
user=root
host=127.0.0.1
password=123456
port=3306

1.读取操作

def readconf():
   
    #读取根目录路径
    root_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    conf.read(root_path+'/test/db.conf','utf8')
    #读取host内容
    dbhost = conf.get('mysql','host')
    print(dbhost)

2.写入操作

def writeconf():
    root_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    conf.read(root_path+ '/test/db.conf','utf8')
    conf.set('mysql','encoding','utf8')
    conf.write(open(root_path+ '/test/db.conf','w'))

如何config文件中没有section，则需要新添一个section

def writeconf():
    root_path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    conf.read(root_path+ '/test/db.conf','utf8')
    #新添section
    conf.add_section('redis')
    conf.set('redis','password','123456')
    conf.write(open(root_path+ '/test/db.conf','w'))
