I'll Show You How To Level Up Your Python Code, And Finally Go Beyond The Basics.
Get Powerful Python Today And Discover How I Use The First Principles Of Python To Write Code At The Top 1% FAANG Level.
Dear Python coder,

My name is Aaron Maxwell and in my book, Powerful Python...

I'd like to show you how I built my Python career in Silicon Valley, and become O'Reilly Media's top Python instructor.

If you write Python code in your job right now...

Or if you have been learning Python, and want to go to the next level...

And especially if you are "sick and tired" of beginner courses which keep teaching you the same boring basics, over and over...

I can show you the powerful "first principles" of Python coding, which allow you to quickly write better code than you ever dreamed possible.

At only 180 pages, and with practical code examples on almost every page.

This is designed to be read and put into action FAST.

Powerful Python is for ambitious Pythonistas who want to level up NOW.
"Among the best books available for taking your Python skills to the next level... I feel there are very few books which offer the sort of insights needed to really improve skills. This is one of the few I can highly recommend for those who are struggling to achieve intermediate skill in Python."
Darrell Fee, USA
"What have I found good and valuable about the book so far? Everything honestly. The clear explanations, solid code examples have really helped me advance as a Python coder... Thank you! It has really helped me grasp some advanced concepts that I felt were beyond my abilities."
Nick S., Colorado
"Feels like Neo learning jujitsu in the Matrix."

What Pythonistas Say About Powerful Python

"I just wanted to let you know what an excellent book this is. I'm a self taught developer and after having done badly at some interviews I decided to buy your book. It covers so many of the interview questions I'd got wrong previously... I keep going back to your book to learn Python. I've actually recommended it as an interview guide to some of my friends."

- Fahad Qazi, London, UK
"Instant productivity gains. These are the best 200 pages you will find on Python if you're an experienced programmer looking to make a leap in your Python skills. The entire book takes only a few days to read, and it's very enjoyable. I'm already seeing the rewards in my code as I have shifted from writing simple scripts with 1-2 normal functions to writing a unit-tested class which creates its own decorated functions at runtime (data-driven), overloads operators, and properly handles and throws exceptions. Nowhere else have I found so many of Python's unique features explained so clearly and succinctly as I have in Powerful Python."

- Carolyn R., USA
"This book is a must have and must read for every Python developer."

- Jorge Carlos, Italy
"A lot of advanced and useful Python features condensed in a single book."

- Giampaolo Mancini, Italy
"Thanks. Keep up the good work. Your chapter on decorators is the best I have seen on that topic."

- Leon Tietz, Minnesota, USA
"It's direct. Goes right for a couple of subjects that have real-world relevance."

- Chuck Staples, Maine, USA
"What have I found good and valuable about the book so far? Everything honestly. The clear explanations, solid code examples have really helped me advance as a Python coder. Thank you! It has really helped me grasp some advanced concepts that I felt were beyond my abilities"

- Nick S., Colorado, USA
"Only a couple chapters in so far but already loving the book. Generators are a game changer."

- Ben Randerson, Aberdeen, UK
"I'm finding your book very insightful and useful... I have greatly benefitted from your rich examples and your extremely clear explanations. Yours is one of the few books I keep on my desk."

- Tony Holdroyd, Gravesend, UK
"Thank you for your book. It is packed with great information, and even better that information is presented in an easy to understand manner... Five stars."

- Jon Macpherson, Pennsylvania, USA
"Your book is absolutely amazing and your ability to articulate clear explanations for advanced concepts is unlike any I have ever seen in any programming book. Thanks again for writing such a good and thought provoking book."

- Armando Someillan
"Great Python book. One of my favorite Python books that show great examples on using the language effectively."

"This is among the best books available for taking your Python skills to the next level. I have read many books on Python programming in a quest to find intermediate level instruction. I feel there are very few books which offer the sort of insights needed to really improve skills. This is one of the few I can highly recommend for those who are struggling to achieve intermediate skill in Python. The author clearly has a mastery of the topic and has an ability to convey it in and understandable way."

- Darrell Fee, USA
"Just what I needed. I think it was pretty excellent. Very much applicable to where I'm at with Python today and taking my coding to the next level... I think you have definitely given me some broad ideas on being able to scale, and some things that I should strive for in my code."

- Josiah Allen, USA
"This book taught me a great deal and was enjoyable to read. The complex patterns are explained well with enough detail to understand but not too much to confuse the reader. After having the book for one day I recommended it to my team and will make it required reading for our interns and junior devs."

- Aaron, USA
"By far one of the best books out there. No nonsense, just great information."

- Edward Finstein, USA
"Great coverage not offered in other books."
