Python读写ini文件

搬运地址: https://www.jb51.net/article/66902.htm

比如有一个文件update.ini，里面有这些内容：

1 2 3 4 5 6 7 8

[ZIP] EngineVersion=0 DATVersion=5127 FileName=dat-5127.zip FilePath=/pub/antivirus/datfiles/4.x/ FileSize=13481555 Checksum=6037,021E MD5=aaeb519d3f276b810d46642d782d8921

那就可以通过下面这些代码得到MD5的值，简单吧

1 2 3 4 5 6 7

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

写也很简单：

1 2 3 4 5 6 7 8 9 10

import ConfigParser config = ConfigParser.ConfigParser() # set a number of parameters config.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 file config.write(open('1.ini', "w"))

修改也不难（添加内容）：

1 2 3 4 5 6 7 8

#!/usr/bin/env python # -*- coding: utf-8 -*- import ConfigParser config = ConfigParser.ConfigParser() config.read('1.ini') a = config.add_section("md5") config.set("md5", "value", "1234") config.write(open('1.ini', "r+")) #可以把r+改成其他方式，看看结果:)

修改内容：

1 2 3 4 5 6 7

#!/usr/bin/env python # -*- coding: utf-8 -*- import ConfigParser config = ConfigParser.ConfigParser() config.read('1.ini') config.set("md5", "value", "kingsoft") #这样md5就从1234变成kingsoft了 config.write(open('1.ini', "r+"))

读写.ini文件的类

from configparser import ConfigParser
import os
from demo import settings  # django项目的配置文件


class ReadWriteConfFile(object):
    path = settings.BASE_DIR + os.sep + 'config.ini'  # 可根据需要替换成自己的路径

    @staticmethod
    def get_parser():
        cf = ConfigParser()
        cf.read(ReadWriteConfFile.path, encoding='utf-8')
        return cf

    @staticmethod
    def write_parser(cf):
        f = open(ReadWriteConfFile.path, "w", encoding='utf-8')
        cf.write(f)
        f.close()

    @staticmethod
    def add_section(section):
        cf = ReadWriteConfFile.get_parser()
        all_sections = cf.sections()
        if section in all_sections:
            return
        else:
            cf.add_section(section)
            ReadWriteConfFile.write_parser(cf)

    @staticmethod
    def get_option(section, key):
        cf = ReadWriteConfFile.get_parser()
        return cf.get(section, key)

    @staticmethod
    def set_option(section, key, value):
        cf = ReadWriteConfFile.get_parser()
        cf.set(section, key, value)
        ReadWriteConfFile.write_parser(cf)


if __name__ == '__main__':
    ReadWriteConfFile.add_section('messages')
    ReadWriteConfFile.set_option('messages', 'name', 'sophia')
    x = ReadWriteConfFile.get_option('messages', 'name')
    print(x)
