此模块用于生成和修改常见配置文档，当前模块的名称在 python 3.x 版本中变更为 configparser。
模块---解析配置文件
```cnf [DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no ```
解析配置文件
```py >>> import configparser # 导入模块 >>> config = configparser.ConfigParser() #实例化(生成对象) >>> config.sections() #调用sections方法 [] >>> config.read(‘example.ini‘) # 读配置文件(注意文件路径) [‘example.ini‘] >>> config.sections() #调用sections方法(默认不会读取default) [‘bitbucket.org‘, ‘topsecret.server.com‘] >>> ‘bitbucket.org‘ in config #判断元素是否在sections列表内 True >>> ‘bytebong.com‘ in config False >>> config[‘bitbucket.org‘][‘User‘] # 通过字典的形式取值 ‘hg‘ >>> config[‘DEFAULT‘][‘Compression‘] ‘yes‘ >>> topsecret = config[‘topsecret.server.com‘] >>> topsecret[‘ForwardX11‘] ‘no‘ >>> topsecret[‘Port‘] ‘50022‘ >>> for key in config[‘bitbucket.org‘]: print(key) # for循环 bitbucket.org 字典的key ... user compressionlevel serveraliveinterval compression forwardx11 >>> config[‘bitbucket.org‘][‘ForwardX11‘] ‘yes‘ ```
其它增删改查语法
```python [group1] # 支持的两种分隔符“=”, “:” k1 = v1 k2:v2 [group2] k1 = v1 import ConfigParser config = ConfigParser.ConfigParser() config.read(‘i.cfg‘) # ########## 读 ########## #secs = config.sections() #print(secs) #options = config.options(‘group2‘) # 获取指定section的keys #print(options) #item_list = config.items(‘group2‘) # 获取指定 section 的 keys & values ,key value 以元组的形式 #print(item_list) #val = config.get(‘group1‘,‘key‘) # 获取指定的key 的value #val = config.getint(‘group1‘,‘key‘) # ########## 改写 ########## #sec = config.remove_section(‘group1‘) # 删除section 并返回状态(true, false) #config.write(open(‘i.cfg‘, "w")) # 对应的删除操作要写入文件才会生效 #sec = config.has_section(‘wupeiqi‘) #sec = config.add_section(‘wupeiqi‘) #config.write(open(‘i.cfg‘, "w")) # #config.set(‘group2‘,‘k1‘,11111) #config.write(open(‘i.cfg‘, "w")) #config.remove_option(‘group2‘,‘age‘) #config.write(open(‘i.cfg‘, "w")) ```
练习：通过configparser模块完成以下功能。文件名my.cnf
[DEFAULT] [client] port = 3306 socket = /data/mysql_3306/mysql.sock [mysqld] explicit_defaults_for_timestamp = true port = 3306 socket = /data/mysql_3306/mysql.sock back_log = 80 basedir = /usr/local/mysql tmpdir = /tmp datadir = /data/mysql_3306 default-time-zone = ‘+8:00‘
i、修改时区 default-time-zone = ‘+8:00‘ 为 校准的全球时间 +00:00
import configparser conf =configparser.ConfigParser() conf.read(‘conf.ini‘) conf[‘mysqld‘][‘default-time-zone‘] = ‘+00:00‘ conf.write(open(‘conf.ini‘,‘w‘))
ii、删除 explicit_defaults_for_timestamp = true
1 import configparser 2 3 conf =configparser.ConfigParser() 4 conf.read(‘conf.ini‘) 5 6 7 8 conf.remove_option(‘mysqld‘,‘explicit_defaults_for_timestamp‘) 9 10 conf.write(open(‘conf.ini‘,‘w‘))
iii、为DEFAULT增加一条 character-set-server = utf8
1 import configparser 2 3 conf =configparser.ConfigParser() 4 conf.read(‘conf.ini‘) 5 6 conf[‘DEFAULT‘][‘character-set-server‘] = ‘utf8‘ 7 8 9 conf.write(open(‘conf.ini‘,‘w‘))
