菜鸟学Python(12):怎么读写ini文件   文章指数:0  CSDN Blog推出文章指数概念,文章指数是对Blog文章综合评分后推算出的,综合评分项分别是该文章的点击量,回复次数,被网摘收录数量,文章长度和文章类型;满分100,每月更新一次.比如有一个文件update.ini,里面有这些内容:

[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
#!/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:
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):
#!/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:
#!/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+"))
删除部分(懒得写了,自己看文档):
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.

section)
Remove the specified section from the configuration. If the section in fact existed, return True. Otherwise return False.
