[Python3] INI file read and write

Overview

INI is one of the configuration file formats that we often see.

INI is a file name extension (also commonly used in other systems) in the Microsoft Windows operating system.

INI "initialization (Initial)" is abbreviated. As the term indicates, the INI file is used to initialize or set parameters on the operating system or a specific program.

Its basic form is as follows:

= == = = = = = = Value4

We use the Python configparser module to read and write INI files.

Configparser Read

• Read (filename) reads INI file contents

• Sections () Gets all the sections and returns as a list

• Options (sections) gets all option for the specified section

• Get (section,option) Gets the value of option in section, returned as a string type

Write

• Set (section, option, value) to update the option in sections

Instance

Our husband becomes an INI file and writes the data and then reads it out to show.

#-*-coding:utf-8-*-__author__='Gubei'#Import ModuleImportConfigparserif __name__=="__main__":    #build an object firstConfig =Configparser.

Summary

The INI file scenario is typically used to initialize the configuration file, but you can also use it for data storage if you wish.

To keep a small problem, try encapsulating a generic INI file operation class with your class.
