Python USES ConfigParser to parse instances of ini configuration files

Ini file is a configuration file commonly used in Windows. The main format is:

[Section1]

option1 : value1

option2 : value2

Python provides a simple module, ConfigParser, that can be used to parse files in this form. The ConfigParser module can parse key:value and key=value, for # and; The first line is automatically ignored. It's the comment line. Common functions:

ConfigParser.RawConfigParser()
RawConfigParser Object Are: 
.sections() :  Returns all available section 

.addsection(sectionname)  Add: section 

.set(sectionname, optionname, optionvalue) :   add option 

.hassection(sectionname)  Judge:  

.options(sectionname)  :   return section Under the available option 

.hasoption(sectionname, optionname)  :   judge  

.read(filename)  :   Read the file  

.wrie(filename) :  will RawConfigParser Object is written to a file  

.get(sectionname, optionname)  :   Get the value ,  The default is to return string type  

.getfloat, .getint, .getboolean :  Gets different types of return values, parameters and get The same parameter  

.items(sectionname)  List: section Of all the key : value 

.remove(sectionname)  : delete section 

.remove(sectionname, option_name)  :   delete section Under a certain option

Demo -- generate files

$ cat ini_demo.py

# -*- coding:utf-8 -*-
import ConfigParser
def gen_ini():

    ftest = open('test','w')

    config_write = ConfigParser.RawConfigParser()

    config_write.add_section('Section_a')

    config_write.add_section('Section_b')

    config_write.add_section('Section_c')

    config_write.set('Section_a','option_a1','apple_a1')

    config_write.set('Section_a','option_a2','banana_a2')

    config_write.set('Section_b','option_b1','apple_b1')

    config_write.set('Section_b','option_b2','banana_b2')

    config_write.set('Section_c','option_c1','apple_c1')

    config_write.set('Section_c','option_c2','banana_c2')   

    config_write.write(ftest)

    ftest.close()
if __name__ == "__main__":

    gen_ini()

The final generated file is:

$ cat test

[Section_a]

option_a1 = apple_a1

option_a2 = banana_a2
[Section_c]

option_c2 = banana_c2

option_c1 = apple_c1
[Section_b]

option_b1 = apple_b1

option_b2 = banana_b2

Demo --  Read the file 
def read_ini():

    config_read = ConfigParser.RawConfigParser()

    config_read.read('test')

    print config_read.sections()

    print config_read.items('Section_a')

    print config_read.get('Section_a','option_a1')

The final result is:

['Section_a', 'Section_c', 'Section_b']

[('option_a2', 'banana_a2'), ('option_a1', 'apple_a1')]

apple_a1
