python 3.4.4

RawConfigParser方式

example.cfg文件：

[Section1] an_int = 15 a_bool = true a_float = 3.1415 baz = fun bar = Python foo = %(bar)s is %(baz)s!

test_example_ini.py 文件：

import configparserdef test_write():config = configparser.RawConfigParser()config.add_section('Section1')config.set('Section1', 'an_int', '15')config.set('Section1', 'a_bool', 'true')config.set('Section1', 'a_float', '3.1415')config.set('Section1', 'baz', 'fun')config.set('Section1', 'bar', 'Python')config.set('Section1', 'foo', '%(bar)s is %(baz)s!')with open('example.cfg', 'w',encoding="utf-8") as configfile:config.write(configfile)def test_read():config = configparser.RawConfigParser()config.read('example.cfg')a_float = config.getfloat('Section1', 'a_float')an_int = config.getint('Section1', 'an_int')print (a_float + an_int)if config.getboolean('Section1', 'a_bool'):print (config.get('Section1', 'foo'))if __name__=="__main__":test_write()test_read()

輸出：

18.1415 %(bar)s is %(baz)s!

同時(shí)生成example.cfg文件，內(nèi)容如下：

[Section1] an_int = 15 a_bool = true a_float = 3.1415 baz = fun bar = Python foo = %(bar)s is %(baz)s!

?ConfigParser方式

mysql.cfg 文件內(nèi)容：

[mysqld] user = mysql pid-file = /var/run/mysqld/mysqld.pid skip-external-locking = True old_passwords = 1 skip-bdb = True skip-innodb = False[oracle] user = root password = hello

test_mysql_cfg.py 文件內(nèi)容：

import configparserdef test_write():config = configparser.ConfigParser()config.read('mysql.cfg')config.set("mysqld", "mysql_pass", "123456")config.write(open('mysql.cfg', "w")) def test_read():config = configparser.ConfigParser()config.read('mysql.cfg')s = config.sections()print ('section:', s)o = config.options("mysqld")print ('mysqld:', o)v = config.items("mysqld")print ('mysql:', v)mysql_user = config.get("mysqld", "user")mysql_pid = config.get("mysqld", "pid-file")mysql_old = config.getint("mysqld", "old_passwords")mysql_skipbdb = config.get("mysqld", "skip-bdb")print (mysql_user, mysql_pid, mysql_old, mysql_skipbdb)if __name__=="__main__":test_write()test_read()

執(zhí)行結(jié)果：

section: ['mysqld', 'oracle'] mysqld: ['user', 'pid-file', 'skip-external-locking', 'old_passwords', 'skip-bdb', 'skip-innodb', 'mysql_pass'] mysql: [('user', 'mysql'), ('pid-file', '/var/run/mysqld/mysqld.pid'), ('skip-external-locking', 'True'), ('old_passwords', '1'), ('skip-bdb', 'True'), ('skip-i nnodb', 'False'), ('mysql_pass', '123456')] mysql /var/run/mysqld/mysqld.pid 1 True

同時(shí)mysql.cfg變化如下：

[mysqld] user = mysql pid-file = /var/run/mysqld/mysqld.pid skip-external-locking = True old_passwords = 1 skip-bdb = True skip-innodb = False mysql_pass = 123456[oracle] user = root password = hello
