PowerShell is a go-to scripting language for almost ANYTHING! Now, if you’re hoping to learn Python, then you’re in the right place. As you start this course, you’ll begin to notice that there are a lot of patterns and concepts shared between the two languages. 

Thus during this course, you will easily be able to relate new Python concepts to the concepts you already know in PowerShell, a learning style called Associative Learning. 

This PowerShell Scripting guide to Python is designed to make you familiar with syntax, semantics, and core concepts of the Python language. And by using concepts you already know in PowerShell, you’ll be able to learn Python fast and effectively in a way that sticks with you for a longer period of time.

Learning Python through PowerShell Concepts

# Parsing JSON

Parsing data in a JSON format in PowerShell is as easy as piping the JSON string to the `ConvertTo-JSON` cmdlet. This emdlet will automatically parse the JSON content and return the PowerShell objects, as in the following example.



$json_string = '{"first": "Prateek", "last":"Singh"}'

## parses the JSON string to objects
$parsed_json = $json_string | ConvertFrom-Json

## accessing the parsed JSON data
$parsed_json.first

Python, on the other hand, has an inbuilt module known as `json` to parse data in JSON formats and files. Simply import this module and use the `loads()` function which will return Python objects after parsing the JSON data.



import json

json_string = '{"first": "Prateek", "last":"Singh"}'

## loads and parses the JSON
parsed_json = json.loads(json_string)

## accessing the parsed JSON like a hash table
print(parsed_json['first'])



# JSON Serialization and Deserialization

In order to store and maintain data in JSON format, both PowerShell and Python support serialization which can convert objects into JSON formatted data files. PowerShell has a `ConvertTo-JSON` cmdlet which converts any object to a JSON equivalent that can then be piped to a file to be written using the `Out-File` cmdlet. In the following example, we serialize PowerShell objects to a JSON formatted file.

> **Note:** Run the `cat jfile.json` command after hitting the "Run" button to see the output.
