Python using the ConfigParser module to manipulate configuration files

This article example describes how Python uses the ConfigParser module to manipulate configuration files. Shared for your reference, as follows:

I. Introduction

Used to generate and modify common configuration documents, the name of the current module has changed in the python version toconfigparser。

II. Configuration file format

[DEFAULT]
ServerAliveInterval = 45
Compression = yes
CompressionLevel = 9
ForwardX11 = yes
[]
User = hg
[]
Port = 50022
ForwardX11 = no

III. Creating configuration files

import configparser
# Generate a processing object
config = ()
# Default Configuration
config["DEFAULT"] = {'ServerAliveInterval': '45',
           'Compression': 'yes',
           'CompressionLevel': '9'}
# Generate additional configuration groups
config[''] = {}
config['']['User'] = 'hg'
config[''] = {}
topsecret = config['']
topsecret['Host Port'] = '50022' # mutates the parser
topsecret['ForwardX11'] = 'no' # same here
config['DEFAULT']['ForwardX11'] = 'yes'
# Write to configuration file
with open('', 'w') as configfile:
  (configfile)

IV. Reading configuration files

1、Read node information

import configparser
config = ()
('')
# Read default configuration node information
print(())
#Read other nodes
print(())

exports

OrderedDict([('compression', 'yes'), ('serveraliveinterval', '45'), ('compressionlevel', '9'), ('forwardx11', 'yes')])
['', '']

2. Read whether the configuration node name exists

print('ssss' in config)
print('' in config)

exports

False
True

3、Read the information inside the configuration node

print(config['']['user'])

exports

hg

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

for key in config['']:
  print(key, ':', config[''][key])

exports

user : hg
compression : yes
serveraliveinterval : 45
compressionlevel : 9
forwardx11 : yes
