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

## Variables

A variable is a unit of memory, typically used to store values like results from commands, expressions, paths, strings, settings, etc.

There is no need to explicitly define data types during the variable declaration in Powershell and Python, because both are **dynamically typed** programming languages. That means the data type of a variable is interpreted during the run time, depending upon the value the variable is holding.

## Rules for naming PowerShell variables

The following rules must be observed when declaring a variable in the Python language:

* PowerShell variable names are represented by text that begins with a dollar sign ( `$` ).
* Variable names are case-insensitive, which means `$var`, `$Var` and `$VAR` represent the same unit of memory to store data.
* Variable names can include spaces and special characters, but these are difficult to use and are not very intuitive so can generally be avoided.

    ```PowerShell
    PS C:\> ${this is a variable} = 12
    PS C:\> ${this is a variable}
    12
    ```
Run the following script to see its output:

# Rules for naming PowerShell variables

The following rules must be observed when declaring a variable in the Python language:

* PowerShell variable names are represented by text that begins with a dollar sign ( `＄` ).
* Variable names are case-insensitive, which means `＄var`, `＄Var` and `＄VAR` represent the same unit of memory to store data.
* Variable names can include spaces and special characters, but these are difficult to use and are not very intuitive so can generally be avoided.

    ```PowerShell
    PS C:\> ＄{this is a variable} = 12
    PS C:\> ＄{this is a variable}
    12
