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

Built-in functions in a programming language are very useful and can be a huge advantage in day-to-day tasks since we don’t have to write them ourselves . Python has a lot of functions built into it that are always available. Similarly, PowerShell has access to .Net classes that brings some useful functions as well. In this lesson, we are going to cover various built-in functions provided by PowerShell and Python.

# Basic Mathematical Operations

We'll come across various day-to-day tasks where it is required to perform basic mathematical operations. Let’s look into them one at a time.





## Constants: PI and E

Mathematical constant `Pi = 3.141592` and Euler’s number(`e = 2.718281`) can be accessed in PowerShell using the `System.Math` class. This has static properties holding values of these constants as shown in the following example.



Likewise, Python has a `math` module that can be utilized to access the values of these constants.

Python:



import math
print(math.pi)
print(math.e)




## Count and Sum: `len()` and `sum()`

PowerShell by default adds a property `length` to containers like an array. They also have  an alias named count that can be utilized to get the `count` of items in an array.
