Dear fellow Python-er,

If you've already mastered the basics of Python...

If you're yawning your way through those beginner courses and books, eternally reviewing what you already know...

If you're eager to see how Python can be used in more complex, interesting, and above all REALISTIC ways....

"Powerful Python Code Walkthroughs" Is Just For You.

Here's the deal:

"Code Walkthroughs" is a collection of high-impact code review videos, each shining a spotlight on a code snippet, class, or short computer program...

Pulled from REAL professional software solving complex, real-world, production-grade problems...

Written by an experienced software engineer and skilled, world-class Pythonista. With the author going through line by line, narrating in careful detail not just how it works, but WHY it was designed that way, and how it fits in the larger application.

Like having a senior Pythonista as your personal mentor.

The full collection is over two hours of video (not including code exercises). However, you'll want to go through each video a minimum of five times to fully absorb it all.

What You're Going To See In Action:

• Nuanced discussions of the trade-offs experienced Python developers make every day... the "secrets" that are rarely discussed outside of close mentoring relationships
• Real-world demonstrations on how to seamlessly weave scalability into your code
• Sidestepping "memory bottlenecks" that threaten to shove your performance off a cliff
• How to "cheat" around Python's "only one constructor" rule
• Examples of "warts" that you want to deliberately leave in your code, and how doing so lets you focus on bigger and better things
• Creating compelling convenience methods to make integrating with the rest of your application easy peasy
• Delightful ways to use "magic methods" that will make your code impressively readable and clear
• Practical, powerful ways to work with one of the most important data formats on the planet today
• How to create a "helper" tool that's quick to code up, easy to improve, and performs valuable, useful tasks in a dozen lines of main-block code
• A relentless parade of demos of weaving multiple advanced Python features together in explosively powerful ways
• An example of creating command-line tools leveraging powerful shortcuts for working with files
• Sober-headed discussions of practical "get it done" trade-offs vs. ivory tower purity
• The remarkable, surprising power that can come from deliberately restricting your code
• An object life-cycle "hack" for automating resource cleanup actions
• Solidly grounded points on readability trade-offs
• Discerning when code documentation is CRITICAL rather than a "nice to have"
• Using internal "one-shot" functions to exponentially improve code clarity
• The psychology of code-level UX, and how it unlocks your inner "elite Pythonista"
• Creating robust data privacy in a scalable, way
• How to use "internal state" techniques to turn a slow, plodding two-pass algorithm into speedy-fast one-pass
• Leveraging built-in Python scalability upgrade data processing throughput
• What a rarely used magic method tells us about the human mind (and how it relates to refactoring)
• An important lesson about self-sufficiency as a developer... and how to avoid the fate of eternally mediocre coders who never learn it
• Priceless skills for analyzing code "out of context"
• A simple one-line trick you can stick almost anywhere in your code... that will leave the worst kinds of "submarine" bugs fully exposed and defenseless
• And a whole lot more, including...

Coding Exercises

As uniquely insightful as these code-walkthrough videos are... it's not enough.

The way you REALLY get the lessons is by writing code.

And we've got ya. With a few simple but powerful coding exercises, that help you "finish the job" of installing the deep lessons, deep in your brain.

Simply by typing the critical code sections explained, forcing your unconscious mind to bind what you've learned. With self-grading code tests baked in, to keep you on the straight and narrow.

It's a quick way to "install" what you're learning, so you can more easily put it into action right away.

What's Included

The code in each video is deliberately short; the longest weighing in at fewer than 150 lines of pithy, expressive, remarkably powerful code.

Because Python is such a high-level language, you can do a LOT with a few lines of well-written code. And we dive deep into each one.

The videos you get include:

#1. A Powerful Abstraction

The first video examples a single Python class, pulled from an internal marketing analytics application. A class representing a powerful abstraction in the code.

This remarkable class uses several advanced features of Python, interlocked in elegant, sophisticated ways...

And in this first video, the developer who created it goes through each part of it, line by line, method by method...

Detailing how this class operates in the context of the larger application...

How it uses class methods, the iterator protocol, and magic methods hooking into standard Python syntax...

And more intriguingly, the psychology around WHY this class arose... How the developer recognized the "hole" in his code this class could fill, and the need for it emerged.

This elegant class, only a few dozen lines long, demonstrates remarkable complexity and Pythonic power. Of course, this is just the first video...

#2. Command-line tool

Next is a command line tool. A utility program specifically created for customer source information extraction.

Again: ALL of these examples come from REAL production software systems.

Reading this far, you don't need the "training wheels" of specially-constructed code snippets created by some "teacher" who can't get a real coding job.

We're going for "forged in the real world"... With pro-grade requirements uncompromising deadlines...

And that makes this little command-line program FAR more valuable than any "toy code" script, and worth studying in detail...

The analysis of this program illustrating command-line UI factors....

While the "guts" of the program give the opportunity to use one of Python's most underappreciated data structures...

As well as teaching some practical trade-offs that come with processing CSV files... One of the most common and important data-interchange formats on the planet...

But digging far "under the surface", where the talented top-tier developer who created it explains how he designed it for SCALABILITY...

Gracefully handling CSV files that are megabytes, gigabytes, even TERABYTES in size... Gracefully, with a shockingly small tiny memory footprint...

And explaining how it's designed for PERFORMANCE... The choices made in terms of arch/idioms/in between

This little program for big data is a perfect demonstration of why...

Python Packs a Punch!

Because anyone can write a large program by just mindlessly writing code long enough...

But mastery of a masterful programming language like Python, lets you do more with less...

And all the valuable, priceless lessons from that extend even to mid-size applications and large, distributed software systems...

Making every video in this collection tremendously valuable...

Bringing us to the next video, the next nugget...

#3. Browser Automation Helper Class

Here's an insightful analysis and breakdown of another important class...

A key component of a web-browser automation tool, originally used to download lead-generation reports from a vendor's website...

And it's another powerful example of a realistic abstraction in a complex codebase...

Yet completely different from the examples above... And thus, teaching exciting new lessons...

Including safe clean-up of filesystem operations...

And more importantly, explaining the thinking BEHIND it... The mindset that creates robust, secure code that avoids unexpected bugs and failure modes...

Demonstrations of how to use code documentation the "right" way, in the context of a complex code base...

And how to precisely define the "boundaries" under which code can operate well and safely...

Plus how using internal functions improves readability and maintainability, in a real-world use case... Again, no toy code here...

And showing you a powerful encapsulation "trick" you may never have even seen before...

#4 and More: Bonus Videos

Including:

• An "email anonymizer" created to privacy-protect the production data used in video #2
• A breakdown of a single interesting method, from a class in a marketing-automation program... And the lessons it can teach us about quickly understanding code with incomplete information
• And MORE planned for the future. Included in your purchase with no additional cost
