Write Better Python Faster.
If You Already Know Python's Basics...
This $5 EBook Will Make You Feel More Confident With Python Than Ever Before. Starting Today.
Three Keys to Better Python
IMPORTANT NOTE:
This is NOT for people brand new to Python.
It assumes you can write simple Python programs using functions, dicts and lists.
If that describes you, here is what you will learn:
Key #1: Clarity With OOP
You probably know that object-oriented programming helps you organize your code.
But more importantly:
OOP helps you THINK BETTER about your code.
Crafting your code so it is easier to reason about, with clarity and insight and power.
What You Learn:
- Starting with a rapid review of the syntax for writing classes in Python...
- Clarifying terminology and dispelling the mystery surrounding the "jargon" of OOP...
- Quickly progressing to a deeper lesson on more powerful features of Python's object system...
- With a particular focus on how different features multiply together across different related classes...
- With practical code examples that are complex enough to relate to realistic code...
- While being simple enough to clearly demonstrate the potent and valuable concepts you are learning...
- With insights into how classes relate to Python's built-in type system.
Class-defined variables let you use inheritance in exciting and powerful ways.
Key #2: Flow States From Automated Testing
You don't need this for simple Python code...
But if you want to write powerful programs and tackle complex codebases, automated testing is for you.
What most people do not know: test-driven development helps you get in a State Of Flow.
So you are "in the zone", locked in, writing better code faster. And quickly completing even the most complex tasks.
What You Learn:
- What makes writing automated tests a superpower used every day by the top 1% elite Python developers worldwide...
- And showing how you can leverage it to create expressive, rich code, more powerful than ever before
- The key distinctions in different kinds of automated tests
- What kinds of code unit tests are most valuable for
- The basic structure of a practical unit test
- Python's built-in tooling for writing powerful tests
- The all-important reporting and code organization features for tests
Well-designed unit tests help you debug faster, by pinpointing errors and highlighting how to fix them.
Key #3: Scaling With Generators
We are in the age of "big data". Especially with AI being more important than ever.
And here's a software engineering tip: If your program has any kind of memory bottleneck, It can reduce performance by a staggering 80% or more.
Yes, 80%!
This is called "paging to disk". And you want to avoid it whenever you can.
The good news: Python generators let you do that. So your program runs better and faster.
What You Learn:
- The dangers of hidden "memory bottlenecks" that will forever change how you look at your own Python code
- The two types of big problem these memory bottlenecks will cause
- The strange yet powerful mutation you can make to ordinary functions... holding the secret to gracefully handling large data sizes
- The "vocabulary fail" almost every single blog post about Python generators gets completely wrong
- A enlightening example from the most challenging kind of program a human can possibly create
Generators make it easy to avoid hidden memory bottlenecks in your code, that would otherwise shove your performance off a cliff!

Roadmaps For Mastery
After each Key, you get a section of bonus content:
A Roadmap for taking it to the next level.
Because this book is short, and designed to give you "quick wins" that you can put into action TODAY...
And I know that once you start seeing these immediate gains in your code quality, confidence, and Pythonic ability...
You will be eager to improve more.
That is why you get three "Roadmap" sections... One for each Key... So you know exactly what to focus on next to keep going.
You also get several Bonuses:
Bonus Key #1:
Higher-Level Collections
When you buy Three Keys to Better Python today, you get a valuable bonus:
A Bonus Supplement teaching a whole extra Key!
This "bonus booklet" includes a chapter on higher-level collections...
Starting with List comprehensions, which are a high-level and declarative way to create a new list in Python.
And it continues beyond the basics of this fun and valuable Python feature, teaching you more advanced comprehension tricks and techniques...
Including exercises to sharpen your learning and test your new skills.
This is not part of the Three Keys book. Instead, it is part of a free bonus supplement e-booklet you receive when you buy today.
Bonus Key #2:
Pythonic Design Patterns
This Bonus covers three new features of Python's object system - going beyond what you learn in Three Keys to Better Python.
- You will learn about a powerful Python feature called properties, and how it can help especially when you need to refactor your code.
- You will learn about "class methods" in Python, and why they are so important for supporting alternative instantiation...
- And you will learn about factory patterns, and how to support them the Python way.
I do feel like I am giving away too much in this Bonus Key. So I may remove it in the future.
But for now, this is your free bonus when you purchase Three Keys to Better Python today.

Questions And Answers
- Who is this for?
-
Three Keys to Better Python is for any Python coder who is already writing simple Python scripts, and is ready to “level up”. In just a few hours, you will MASSIVELY improve your thinking about realistic, complex Python code, and feel an immediate difference in how you work day-to-day with Python.
- Who is this NOT for?
-
Three Keys is NOT for people brand new to programming. It assumes you have mastered the “basics” of Python, and are sick and tired of hello-world level “hand holding”. If you have never written Python code before, it is better to find something for beginners.
- How long is the ebook?
-
About 30 pages, including all diagrams and code blocks. This book includes plenty of code examples to illustrate what you learn, and help you apply it right away.
