configparser模块
Python 解析配置模块之ConfigParser详解
1.基本的读取配置文件
-read(filename) 直接读取ini文件内容
-sections() 得到所有的section,并以列表的形式返回
-options(section) 得到该section的所有option
-items(section) 得到该section的所有键值对
-get(section,option) 得到section中option的值,返回为string类型
-getint(section,option) 得到section中option的值,返回为int类型,还有相应的getboolean()和getfloat() 函数。
2.基本的写入配置文件
-add_section(section) 添加一个新的section
-set( section, option, value) 对section中的option进行设置,需要调用write将内容写入配置文件。
3.基本例子
配置文件
[DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no
生成一个配置文件:
import configparser config = configparser.ConfigParser() config["DEFAULT"] = {'ServerAliveInterval': '45', 'Compression': 'yes', 'CompressionLevel': '9'} config['bitbucket.org'] = {} config['bitbucket.org']['User'] = 'hg' config['topsecret.server.com'] = {} topsecret = config['topsecret.server.com'] topsecret['Host Port'] = '50022' # mutates the parser topsecret['ForwardX11'] = 'no' # same here config['DEFAULT']['ForwardX11'] = 'yes' with open('example.ini', 'w') as configfile: config.write(configfile)
增删改查
[section1]
k1 = v1
k2:v2
[section2]
k1 = v1
import ConfigParser
config = ConfigParser.ConfigParser()
config.read('i.cfg')
# ########## 读 ##########
#secs = config.sections()
#print secs
#options = config.options('group2')
#print options
#item_list = config.items('group2')
#print item_list
#val = config.get('group1','key')
#val = config.getint('group1','key')
# ########## 改写 ##########
#sec = config.remove_section('group1')
#config.write(open('i.cfg', "w"))
#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"))
