一写入一个配置文件:

import configparser

# 写入一个配置文件

# 得到一个configparser对象

conf=configparser.ConfigParser()

conf["TOM"]={

"age":20,

"like":"gril"

}

conf['Lili']={

"age":30,

"like":"man"

}

with open("people.ini","w")as f:

conf.write(f)

二:读取并修改配置文件

import configparser
#读取配置文件信息
conf = configparser.ConfigParser() #获得一个configparser.ConfigParser对象
conf.read('example.ini') #将内容读到对象中,而不是给出返回值,返回值为 ['example.ini']
conf.sections() #['bitbucket.org', 'topsecret.server.com']
conf.options('bitbucket.org')#['user', 'compression', 'compressionlevel', 'serveraliveinterval', 'forwardx11']
#需要注意的事情:
# conf.options('DEFAULT') #会报错！！！！
conf.items('bitbucket.org')
"""
[('compression', 'yes'),
('compressionlevel', '9'),
('serveraliveinterval', '45'),
('forwardx11', 'yes'),
('user', 'hg')]
"""
# 得到值的两种方式,这两种方式在取值错误的时候都会报错.23333333
conf.get('bitbucket.org','compression')
conf.get( 'DEFAULT','compression')
conf['bitbucket.org']['compression']
conf.set('bitbucket.org','compression',"asdsfasd") #修改值
conf['bitbucket.org']['compression']="asdfa" #修改值
conf.get( 'DEFAULT','compression') #只能拿到值
with open("2333.ini","w")as f:
conf.write(f)

In [28]: help(conf.sections)

Help on method sections in module configparser:

sections() method of configparser.ConfigParser instance

Return a list of section names, excluding [DEFAULT]

In [29]: help(conf.read)

Help on method read in module configparser:

read(filenames, encoding=None) method of configparser.ConfigParser instance

Read and parse a filename or a list of filenames.

Files that cannot be opened are silently ignored; this is

designed so that you can specify a list of potential

configuration file locations (e.g. current directory, user's

home directory, systemwide directory), and all existing

configuration files in the list will be read. A single

filename may also be given.

Return list of successfully read files.

	获取值,不存在的时候会报错	In [50]: conf.get('DEFAULT','compression') Out[50]: 'yes'
	判断是否是布尔类型,不是布尔类型时候报错	In [56]: conf.getboolean('DEFAULT','forwardx11') Out[56]: True
has_option	判断有没有这个 option	In [63]: conf.has_option(conf.default_section,"sadf") Out[63]: False
has_section	判断有没有这个 section
clear	清空sections 只会清空非'DEFAULT'	In [67]: conf.clear() In [68]: conf.sections() Out[68]: []
Iteams	类似于dick中的 Iteams用法	In [82]: it=conf.items() In [83]: for key,value in it: ...: print(key,value) ...: DEFAULT <Section: DEFAULT> bitbucket.org <Section: bitbucket.org> topsecret.server.com <Section: topsecret.server.com> TOM <Section: TOM> Lili <Section: Lili>
keys		In [86]: for i in conf.keys(): ...: print(i) ...: DEFAULT bitbucket.org topsecret.server.com TOM Lili
options	需要传入一个值这个值是section的值, 字符串类型	In [104]: conf.options('bitbucket.org') Out[104]: ['user', 'compression', 'compressionlevel', 'serveraliveinterval', 'forwardx11']
sections	获得sections	In [107]: conf.sections() Out[107]: ['bitbucket.org', 'topsecret.server.com', 'TOM', 'Lili']
