Python Libraries for DevOps

Reading JSON and YAML in Python

• As a DevOps Engineer, you should be able to parse files, be it Txt, json, yaml, etc.

• You should know what libraries one should use in Python for DevOps.

• Python has numerous libraries like os, sys, json, yaml etc that a DevOps Engineer uses in day-to-day tasks.

Tasks

1. Create a Dictionary in Python and write it to a JSON File.

This code is the conversion of PYTHON →JSON using JSON.dumps()

import json

data_dict = {
    1:"Linux",
    2:"Git",
    3:"Docker",
    4:"Kubernetes",
    5:"Terraform",
    6:"Ansible",
    7:"Chef"
    }
json_object = json.dumps(data_dict, indent= 4)
print("Json format :\n",json_object)

1. Read a json file services.json kept in this folder and print the service names of every cloud service provider.

Output:

1. YAML file using Python, file services.yaml and read the contents to convert yaml to json

2. Use the PyYAML module’s yaml.load() function. This function parses and converts a YAML object to a Python dictionary

To install the pyYAML module :

pip install pyYAML

The below code will help us convert a yaml file into Python and then into Java

The output will be in JSON form
