ConfigParser----模块

〇:配置文件管理模块:

help(configparser.ConfigParser)

 

| ConfigParser

| RawConfigParser

| collections.abc.MutableMapping

| collections.abc.Mapping

| collections.abc.Sized

| collections.abc.Iterable

| collections.abc.Container

| builtins.object

dir(conf)

'clear', 'converters', 'default_section', 'defaults', 'get', 'getboolean', 'getfloat', 'getint', 'has_option', 'has_section', 'items', 'keys', 'options', 'optionxform',

'read_file', 'read_string', 'readfp', 'remove_option', 'remove_section', 'sections', 'set', 'setdefault', 'update', 'values', 'write' 'pop', 'popitem', 'read', 'read_dict',

 

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

1. import configparser  
2. #读取配置文件信息  
3. conf = configparser.ConfigParser()  #获得一个configparser.ConfigParser对象  
4. 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']  
5. conf.sections() #['bitbucket.org', 'topsecret.server.com']  
6. conf.options('bitbucket.org')#['user', 'compression', 'compressionlevel', 'serveraliveinterval', 'forwardx11']  
7. #需要注意的事情:  
8. # conf.options('DEFAULT')  #会报错！！！！  
9. conf.items('bitbucket.org')  
10. """ 
11.                             [('compression', 'yes'), 
12.                              ('compressionlevel', '9'), 
13.                              ('serveraliveinterval', '45'), 
14.                              ('forwardx11', 'yes'), 
15.                              ('user', 'hg')] 
16. """  
17. # 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  
18. conf.get('bitbucket.org','compression')  
19. conf.get( 'DEFAULT','compression')  
20.     
21. conf['bitbucket.org']['compression']  
22.     
23. conf.set('bitbucket.org','compression',"asdsfasd") #修改值  
24. conf['bitbucket.org']['compression']="asdfa" #修改值  
25. conf.get( 'DEFAULT','compression') #只能拿到值  
26. with open("2333.ini","w")as f:  
27.     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']
