 1、生成配置文件

\'\'\' 
    生成配置文件
\'\'\'
import configparser

config = configparser.ConfigParser()

# 初始化赋值
config["DEFAULT"] = {\'ServerAliveInterval\': \'45\',
                      \'Compression\': \'yes\',
                     \'CompressionLevel\': \'9\'}
# 追加
config[\'DEFAULT\'][\'ForwardX11\'] = \'yes\'

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

with open(\'example.ini\', \'w\') as configfile:
   config.write(configfile)

　　生成的配置文件 example.ini

[DEFAULT]
serveraliveinterval = 45
compression = yes
compressionlevel = 9
forwardx11 = yes

[bitbucket.org]
user = hg

[topsecret.server.com]
host port = 50022
forwardx11 = no

 

2、读取配置文件

# 读
import configparser
config = configparser.ConfigParser()
config.sections()

config.read(\'example.ini\')

# {\'serveraliveinterval\': \'45\', \'compression\': \'yes\', \'compressionlevel\': \'9\', \'forwardx11\': \'yes\'}
print(config.defaults())

# hg
print(config[\'bitbucket.org\']["User"])

# 50022
print(config["topsecret.server.com"]["host port"])

 

3、删除

# 删除（创建一个新文件，并删除 bitbucket.org）
import configparser
config = configparser.ConfigParser()
config.sections()

config.read(\'example.ini\')
rec = config.remove_section("bitbucket.org") # 删除该项
config.write(open("example.cfg","w"))

　　生成新文件 example.cfg

DEFAULT]
serveraliveinterval = 45
compression = yes
compressionlevel = 9
forwardx11 = yes

topsecret.server.com]
host port = 50022
forwardx11 = no

　　删除，并覆盖原文件

# 删除（删除 bitbucket.org）
import configparser
config = configparser.ConfigParser()
config.sections()

config.read(\'example.ini\')
rec = config.remove_section("bitbucket.org") # 删除该项
config.write(open("example.ini","w"))

 

4、修改

import configparser

config = configparser.ConfigParser()

config.read(\'example.ini\')  #读文件

config.add_section(\'yuan\')  #添加section

config.remove_section(\'bitbucket.org\') #删除section
config.remove_option(\'topsecret.server.com\',"forwardx11") #删除一个配置项

config.set(\'topsecret.server.com\',\'k1\',\'11111\')
config.set(\'yuan\',\'k2\',\'22222\')
with open(\'new2.ini\',\'w\') as f:
     config.write(f)

　　生成新文件 new2.ini

[DEFAULT]
serveraliveinterval = 45
compression = yes
compressionlevel = 9
forwardx11 = yes

[topsecret.server.com]
host port = 50022
k1 = 11111

[yuan]
k2 = 22222
