configparser的用法

这是一个简单的配置文件

[SectionOne]
Status: Single
Name: Derek
Value: Yes
Age: 30
Single: True

[SectionTwo]
FavoriteColor = Green
[SectionThree]
FamilyName: Johnson

[Others]
Route: 66
解析如下

>>> import ConfigParser
>>> Config = ConfigParser.ConfigParser()
>>> Config
<ConfigParser.ConfigParser instance at 0x00BA9B20>
>>> Config.read("c:\tomorrow.ini")
['c:\tomorrow.ini']
>>> Config.sections()
['Others', 'SectionThree', 'SectionOne', 'SectionTwo']
>>>

程序

def ConfigSectionMap(section):
    dict1 = {}
    options = Config.options(section)
    for option in options:
        try:
            dict1[option] = Config.get(section, option)
            if dict1[option] == -1:
                DebugPrint("skip: %s" % option)
        except:
            print("exception on %s!" % option)
            dict1[option] = None
    return dict1

读取

>>> Name = ConfigSectionMap("SectionOne")['name']
>>> Age = ConfigSectionMap("SectionOne")['age']
>>> print "Hello %s. You are %s years old." % (Name, Age)
Hello Derek. You are 30 years old.

要读布尔变量

>>> single = Config.getboolean("SectionOne", "single")
>>> single
True

写配置文件

# lets create that config file for next time...
cfgfile = open("c:\next.ini",'w')

# add the settings to the structure of the file, and lets write it out...
Config.add_section('Person')
Config.set('Person','HasEyes',True)
Config.set('Person','Age', 50)
Config.write(cfgfile)
cfgfile.close()

读取可变值

[SectionOne]
Param1: Hello
Param2: World

[SectionTwo]
Param1: ${SectionOne:Param1} ${SectionOne:Param2}

[SectionThree]
Alpha: One
Bravo: Two
Charlie: ${Alpha} Mississippi

>>> import configparser
>>> settings = configparser.ConfigParser()
>>> settings._interpolation = configparser.ExtendedInterpolation()
>>> settings.read('settings.ini')
['settings.ini']
>>> settings.sections()
['SectionOne', 'SectionTwo', 'SectionThree']
>>> settings.get('SectionTwo', 'Param1')
'Hello World'
>>> settings.get('SectionThree', 'Charlie')
'One Mississippi'
