Python ConfigParser(python3中是configparser）
包含3个object
RawConfigParser Objects：
有如下方法：
RawConfigParser.defaults()
RawConfigParser.add_section(section)
Add a section named section to the instance
RawConfigParser.sections()
Return a list of the sections available
RawConfigParser.remove_section(section)
Remove the specified section from the configuration
Example:
>>> import ConfigParser
>>> config=ConfigParser.RawConfigParser()
>>> config.defaults()
{}
>>> config.add_section('section1')
>>> config.add_section('section2')
>>> config.sections()
['section2', 'section1']
>>> config.remove_section('section2')
True
>>> config.sections()
['section1']
RawConfigParser.set(section, option, value)
If the given section exists, set the given option to the specified value
RawConfigParser.get(section, option)
Get an option value for the named section.
RawConfigParser.getint(section, option)
A convenience method which coerces the option in the specified section to an integer.
RawConfigParser.getfloat(section, option)
A convenience method which coerces the option in the specified section to a floating point number.
RawConfigParser.getboolean(section, option)
the accepted values for the option are "1", "yes", "true", and "on", which cause this method to return True, and "0", "no", "false", and "off", which cause it to return False.
RawConfigParser.items(section)
Return a list of (name, value) pairs for each option in the given section
RawConfigParser.remove_option(section, option)
Remove the specified option from the specified section
RawConfigParser.write(fileobject)
Write a representation of the configuration to the specified file object
RawConfigParser.read(filenames)
Read and parse a list of filenames, returning a list of filenames which were successfully parsed.
Example：
>>> config.set('section1','a_int','1')
>>> config.set('section1','a_float','1.1')
>>> config.set('section1','a_bool','true')
>>> config.set('section1','name','kyle')
>>> config.getint('section1','a_int')
1
>>> config.getfloat('section1','a_float')
1.1000000000000001
>>> config.getboolean('section1','a_bool')
True
>>>
>>> config.get('section1','name')
'kyle'
>>> f=open('text.txt','wb')
>>> config.write(f)
>>> f.close()
>>> config.read('text.txt')
['text.txt']
>>> for item in config.items('section1'):
... print item
...
('a_int', '1')
('a_bool', 'true')
('name', 'kyle')
('a_float', '1.1')
>>> config.remove_option('section1','a_int')
True
>>> for item in config.items('section1'):
... print item
...
('a_bool', 'true')
('a_float', '1.1')
('name', 'kyle')
ConfigParser Objects(extends some methods of the RawConfigParser interface）：
ConfigParser.get(section, option[, raw[, vars]])
使用方法基本与RawConfigParser.get(section, option)相同，区别如下：
>>> config=ConfigParser.ConfigParser()
>>> config.read('text.txt')
['text.txt']
>>> config.set('section1','tt','%(a_int)s is not equal %(a_float)s')
>>> config.get('section1','tt',1)
'%(a_int)s is not equal %(a_float)s'
>>> config.get('section1','tt',0)
'1 is not equal 1.1'
ConfigParser.items(section[, raw[, vars]])
和RawConfigParser.items(section)中的区别 和get方法一样
SafeConfigParser Objects（implements the same extended interface as ConfigParser）：
SafeConfigParser.set(section, option, value)
Example:
>>> config=ConfigParser.SafeConfigParser({'a_int':'3'})
>>> config.read('text.txt')
['text.txt']
>>> print config.get('section1','a_int')
1
>>> config.remove_option('section1','a_int')
True
>>> print config.get('section1','a_int')
3
