Introduction to configparser

The ConfigParser module has been renamed to configparser in Python 3.
This module defines the ConfigParser class. The ConfigParser class implements a basic configuration file parser language that provides a structure similar to that found in .ini files

ini file related knowledge

Key-value pairs can be separated by = or:;
section names are case-sensitive, while option names are case-insensitive;
leading and trailing blanks in key-value pairs will be removed;
values can be multi-line ;
The configuration file can contain comments, and the comments are prefixed with # or ;;

ini file example

[server]    
age = 45
username = yes

# server就是section
# age、username就是option

Manipulate the ini file

Instantiate the ConfigParser class;
read the configuration file;
operate the configuration file;

base code

import configparser

filename = 'F:/Interface/config/server.ini'
# 实例化configparser
config = configparser.ConfigParser()

# 读取配置文件
config.read(filename, encoding="utf-8-sig")

# 获取某个option的值(最常见的操作)
config.get(section="server", option="username")

When the configuration file has Chinese, when calling the read() method, you need to pass the encoding="utf-8-sig" parameter

The most common operation is get(section,option,fallback="default value") to get the value of an option, of course you can also pass a fallback, when your option does not exist, the value of the fallback will be returned

configparser encapsulation class

In order to better reuse configparser, we write commonly used methods as a wrapper class
