Python parsing ini file by configparser

Python parsing ini file by configparser

INI file is a frequently used configuration file in Windows, the main format is:

[Section1]option1 : value1option2 : value2

Python provides a simple module that ConfigParser can be used to parse files similar to this form. For a ConfigParser module to be resolvable key:value and key=value such a type, the # row for and ; beginning will be ignored automatically. Equivalent to the comment line. Common functions:

Configparser.rawconfigparser ()

The operations of the Rawconfigparser object are:

. Sections () : Returns all the available sections
. Add section(section name) : Adding section
. Set (sectionname, optionname, optionvalue): Add option
. Has sections(section name) : Judging
. Options (sectionname) : Returns the option available under section
. Haveoption (sectionname, optionname) : Judging
. Read (filename) : Read files
. Wrie (filename) : Writes the Rawconfigparser object to a file
. Get (SectionName, optionname) : Gets the value, the default is the return string type
. GetFloat,. Getint,. Getboolean : Get different types of return values, parameters like get parameters
. Items (sectionname) : Lists all Key:value under section
. Remove (sectionname) : Delete section
. Remove (sectionname, option_name) : Delete an option under section

Demo--Generate files

$ cat ini_demo.py# -*- coding:utf-8 -*-import ConfigParserdef 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 last generated file is:

$ cat test[Section_a]option_a1 = apple_a1option_a2 = banana_a2[Section_c]option_c2 = banana_c2option_c1 = apple_c1[Section_b]option_b1 = apple_b1option_b2 = banana_b2

Demo--Read 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
