PowerShell Guide to Python
PowerShell Guide to Python
A Comparative Approach to Learn two Scripting Languages at once. Fast!
About the Book
This PowerShell Scripting guide to Python is designed to make readers familiar with syntax, semantics and core concepts of Python language, in an approach that readers can totally relate with the concepts of PowerShell already in their arsenal, to learn Python fast and effectively, such that it sticks with readers for longer time.
"Use what you know to learn what you don't. " also known as Associative learning.
Book follows a comparative method to jump start readers journey in Python, but who is the target audience? and who should read this book -
- Any System Administrator who want to step into Development or Programming roles, and even if you don't want to be a developer, knowledge of another scripting language will make your skill set more robust.
- Python Developers who want to learn PowerShell scripting and understand its ease of user and importance to manage any platform.
- This book works both ways: As a reader you can use the book to learn Python if you know PowerShell, or learn PowerShell if you know Python. PowerShell and Python code samples and screenshots next to each other makes it very easy for readers to relate the common concepts and practices and learn the scripting language in no time.
Python is one of the top programming languages and in fast changing IT scenarios to DevOps and Cloud to the future - Data Science, Artificial Intelligence (AI) and Machine Learning Python is a must know.
But this PowerShell Scripting guide to Python would be very helpful for you if you already have some knowledge of PowerShell

Good approach to grow-up your knowledge in Python very quickly
Learning Python becomes simple with this book when you come from the PowerShell world. Prateek has really done an awesome work of consolidating into one book what will take you several months to acquire this knowledge by yourself. What I like in this book is this approach to learn a new language from a language you know well. A really a good way to grow-up your knowledge in Python very quickly without too many difficulties.

PowerShell as a segue to Python
As a programmer, I wanted to learn python, but since I am already working on Powershell. So this book was suggested to me which can help me learning python through Powershell. I started reading the book and from the 1st day itself, I found it so interesting, short crisp and simple way to learn something new. I must say this book not only helps in learning python but also pushed me to learn more things in PowerShell as well. Great book, recommended!
