How to read and write INI files using Python

This article describes how to read and write ini files in Python. It provides an example of how to read, write, and modify ini configuration files in Python, for more information about how to read and write INI files in Python, see the following example. Share it with you for your reference. The details are as follows:

For example, an update. ini file contains the following content:

[ZIP]EngineVersion=0DATVersion=5127FileName=dat-5127.zipFilePath=/pub/antivirus/datfiles/4.x/FileSize=13481555Checksum=6037,021EMD5=aaeb519d3f276b810d46642d782d8921

The following code can be used to obtain the MD5 value.

#!/usr/bin/env python# -*- coding: utf-8 -*-import ConfigParserconfig = ConfigParser.ConfigParser()config.readfp(open('update.ini'))a = config.get("ZIP","MD5")print a

Writing is also simple:

import ConfigParserconfig = ConfigParser.ConfigParser()# set a number of parametersconfig.add_section("book")config.set("book", "title", "the python standard library")config.set("book", "author", "fredrik lundh")config.add_section("ematter")config.set("ematter", "pages", 250)# write to fileconfig.write(open('1.ini', "w"))

It is not difficult to modify (add content ):

#! /Usr/bin/env python #-*-coding: UTF-8-*-import ConfigParserconfig = ConfigParser. configParser () config. read ('1. ini ') a = config. add_section ("md5") config. set ("md5'," value "," 1234 ") config. write (open ('1. ini ', "r +") # You can change r + to another method to see the result :)

Modification content:

#! /Usr/bin/env python #-*-coding: UTF-8-*-import ConfigParserconfig = ConfigParser. configParser () config. read ('1. ini ') config. set ("md5", "value", "kingsoft") # in this way, md5 is changed from 1234 to kingsoft config. write (open ('1. ini ', "r + "))

You are too lazy to write the deleted part. If you are interested, read the document:

Remove_option (section, option)
Remove the specified option from the specified section. If the section does not exist, raise NoSectionError. If the option existed to be removed, return True; otherwise return False. New in version 1.6.
Remove_section (section)
Remove the specified section from the configuration. If the section in fact existed, return True. Otherwise return False.

I hope this article will help you with Python programming.
