We need configuration file for arranging and using many information in a nice way. There are many configuration file formats like yaml, ini, etc.

yaml file format

yaml [1] stands for “yet another markup language”. It stores messages in terms of lists and dictionaries. It is optimized for data serialization, configuration settings, log files, etc.

Data can be stored in two types or the combination of these two types. They are:

1. sequences, and
2. mapping.

Sequence referes to :

  - Ram
  - Krishna
  - sharma

And mapping refers to:

  FirstName: Ram
  SecondName: Krishna
  LastName: sharma

There are many ways we can combine these two:

mapping to sequences

Name:
 - Ram krishna sharma
 - Archana Kumari
 - Test1
 - Test2
Test:
 - Test3
 - Test4
 - Test5

sequences to mapping

-
  Name: Ram krishna sharma
  sex: Male
  age: 29
-
  Name: Archana Kumari
  sex: Female
  age: 28

Read yaml file

import yaml

file = open("yamlfile.yml","r")
ymload = yaml.load(file)

for sections in ymload:
  print sections
  print ymload[sections]
