Detailed introduction to the ConfigParser module-Python Tutorial-php.cn

1. Introduction

Used to generate and modify common configuration documents. The name of the current module was changed to configparser in the python 3.x version.

2. Configuration file format

[DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no

3. Create configuration file

import configparser # 生成一个处理对象 config = configparser.ConfigParser() #默认配置 config["DEFAULT"] = {'ServerAliveInterval': '45', 'Compression': 'yes', 'CompressionLevel': '9'} #生成其他的配置组 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' #写入配置文件 with open('example.ini', 'w') as configfile: config.write(configfile)

Copy after login

4. Read the configuration file

1. Read the node information

import configparser config = configparser.ConfigParser() config.read('example.ini') # 读取默认配置节点信息 print(config.defaults()) #读取其他节点 print(config.sections()) # 输出 OrderedDict([('compression', 'yes'), ('serveraliveinterval', '45'), ('compressionlevel', '9'), ('forwardx11', 'yes')]) ['bitbucket.org', 'topsecret.server.com']

Copy after login

2. Determine whether the configuration node name exists

print('ssss' in config) print('bitbucket.org' in config) #输出 False True

Copy after login

3. Read the information in the configuration node

print(config['bitbucket.org']['user']) #输出 hg

Copy after login

4. Loop to read all the information of the configuration node

for key in config['bitbucket.org']: print(key, ':', config['bitbucket.org'][key]) #输出 user : hg compression : yes serveraliveinterval : 45 compressionlevel : 9 forwardx11 : yes
