python 解析模块 configparser

 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
