To Every Python Developer Who’s Tired of
Constantly Reinventing the Wheel
and Found Him or Herself Wondering:

“Which frameworks and libraries are the most important to know to be considered an effective Python dev?”

Here’s How to Go From “Writing Scripts” to
“Building Applications” With Python,
Master the Tools of the Trade for Dependency Management, and Become an Expert At
Picking Quality Python Libraries:

Dear Fellow Python Developer,

Not too long ago PyPI, the Python packaging repository, crossed 100,000 available third-party packages in total.

That’s an overwhelming number of packages to choose from—

And this feeling of overwhelm and “choice paralysis” is exactly what held me back earlier on in my Python career.

Here, let me explain:

Back when I got “serious” about building my Python skills, mastering the syntax of the language was not the hardest part

Python’s syntax seemed quite clear and intuitive by comparison, and I saw a (relatively) obvious path to learning it.

But when it came to Python’s 100k+ libraries and frameworks—

That was simply an OVERWHELMING amount of information to digest.

Even when I knew there had to be a library out there that already solved a problem I was facing—I drew a blank when it came to researching it.

I didn’t know what made a Python library or framework worthwhile.

Everything blended together into a “sea of modules” and I couldn’t winnow out the useless or obsolete—

In short, I was lost when it came to finding and judging the quality of Python libraries.

And so I spun my wheels…

Hi, my name is Dan Bader.

Today I’m an independent software engineer, book author, and speaker. I’ve been writing code for more than 15 years.

Python is my favorite programming language and these days I’m fortunate to get to use Python almost every day in my work.

What tripped me up as a fledgling Pythonista was this—

I had the basics of Python under my belt, but:

Oh hey!

Dan Bader helps Python developers take their coding skills and productivity to the next level. He's an independent software engineer, book author, and speaker and has been shipping software for more than a decade.

I struggled when it came to adopting the right workflows and tools of the “ecosystem” surrounding the core language

Thus, I wasted my time reinventing existing solutions left and right—

Sometimes I spent DAYS writing my own (crappy) versions of common building blocks like config file parsers, data validators, or visualization tools.

Now, sure I learned quite a bit from doing that…

But I kept repeating the same mistake and was “reinventing the wheel” even when under a tight deadline.

In hindsight, my ignorance caused me a ton of undue stress and sleep deprivation.

Part of it was overconfidence in my abilities—and another part was that

I lacked experience using “bread and butter” tools like the pip package manager, virtual environments, and requirements files.

And it prevented me from breaking through to the next phase of developing code in Python.

You see, languages such as C++ that I used before didn’t have an advanced package management system like Python.

Because I was used to “copy-pasting” third-party code into my own projects I missed out on the versioning features in Python packages.

And instead of building applications that combined the power of several specialized building blocks

I strung together messy “copypasta” globs of code that I couldn’t get to run on anyone else’s computer

Today I know I’m not the only developer who had to overcome “reinventing the wheel disease.”

Tragically, it is a hidden roadblock to many aspiring Pythonistas:

What separates experienced Python programmers from learners is that they create new functionality with building blocks they already know.

And leveraging these building blocks requires a vast set of inter-related pieces of knowledge—from packages to deployment:

Now, most “stuck” Python developers are aware of the tools that could help them ascend from “dependency hell”—

But they don’t see how to use them to their advantage.

If you ask a group of junior or intermediate Python developers about their experience you’ll hear things like:

“I’ve heard people say ‘you should always use a virtualenv’ but I don’t really see why. Seems like an additional step I don’t really need…

You see, the problem is this:

Too many Python developers know these tools exist, but they don’t see why they’re important and what makes them so powerful.

And tragically, by ignoring the help that tools like pip, virtualenv, and PyPI provide these developers sabotage their own productivity.

Ask yourself this:

If you use Python and you’re wondering how to go from “writing scripts” to “building applications”—

Then there’s a good chance that

Missing Dependency Management skills are holding you back from your full potential as a Python developer

If you can fill in those gaps in your knowledge your productivity and efficiency as a Python developer will benefit greatly.

That’s what happened to me—

Once I got the hang of Python’s dependency management tools and workflows I was quickly able to shake off my “reinventing the wheel disease.”

I can see now how removing this roadblock triggered a “quantum leap” in my productivity as a software developer.

Here’s the secret:

By leveraging Python’s packaging ecosystem you will be coding at a higher level of abstraction—

Instead of wasting time re-coding tools and functionality that already existed, I was able focus on the business goals.

Figuring this out had a MASSIVE impact on my productivity and efficiency as a Python developer.

Saying it allowed me to “10X” my output wouldn’t be too far off.

Within a month my peers and superiors had noticed my improved productivity—because they saw me tearing through sprint tickets left and right.

It’s one of the easiest and quickest “wins” you can get in your Python career

I’ve seen it happen several times with 1:1 coaching clients and during workshops.

But this kind of training can only reach so many people.

And I wanted every Python developer to be able to take advantage of modern dependency management workflows and tools.

So I got to work…

And now, after months of recording and editing I’m proud to introduce:

  • Module 2 – Managing Third-Party Dependencies With Pip
    Discover how dependency management enables modern software development by making well-packaged building blocks available in your own programs. You’ll start with an introduction to dependency management in Python, including its main benefits and challenges. Then you’ll get hands-on examples for how to work with “pip”, the official Python package manager.

    You’ll learn how to install and update pip, how it’s command line interface works, and how you can use pip to install (and uninstall) third-party packages. You’ll also see how to identify and selectively upgrade outdated dependencies. Besides that you’ll gain a deep understanding of Python’s packaging ecosystem, including the main package repositories like PyPI and Warehouse, as well as advanced version management features in pip.
  • Module 3 – Isolating Dependencies With Virtual Environments
    In this module you’ll discover how leveraging sandboxed Python environments helps you avoid version conflicts and deployment headaches.

    By following along with hands-on live demos you’ll see how to smoothly integrate virtual environments into your Python (2.x or 3.x) development workflow. I’m also sharing my personal command-line workflow and shell setup for making switching between virtual environments a breeze.
  • Module 4 – Finding Quality Python Packages
    In this core module in the course you’ll master how to find and identify quality Python packages. You’ll see how the more than 100,000 third-party packages available today will help you save time, avoid “reinventing the wheel”, and deliver your projects faster.

That’s it for the bonus content included with the full course.

Let’s do a quick recap so you’ll know exactly whether or not Managing Python Dependencies is right for you:

Course Goals:
By the End of the Course You’ll Know How To:

  • Install, use, and manage third-party Python packages with the “pip” package manager on Windows, macOS, and Linux.
  • Isolate project dependencies with so-called virtual environments to avoid version conflicts in your Python projects.
  • Apply a complete 7-step workflow for finding and identifying quality third-party packages to use in your own Python projects (and justifying your decisions to your team or manager.)
  • Set up repeatable development environments and application deployments using the “pip” package manager and requirements files.

Who Should Take This Course?

  • This course is for Python developers wanting to break through to the next phase of developing code by becoming more efficient, productive, and skilled using Python’s rich library ecosystem.
  • If you’ve ever caught yourself thinking “There’s got to be a Python package out there that does exactly what I want…But how do I find it?” this course will fill in the missing pieces for you. Discover the industry best practices around choosing and managing third-party dependencies for your Python 2 or Python 3 projects.
  • If you already know how to use alternative package managers like Conda you’ll discover how to use the standards-compliant tools and workflows supported by any Python distribution and used in most production application deployments.

Who Should Not Take This Course:

  • This course is probably not for you if you already have an in-depth understanding of how packaging works in Python, you’re 100% happy with your current workflow for managing dependencies, you know how to find and identify quality Python packages for any situation, and you you can easily justify your decisions to your team or manager.

You May Be Wondering,
How Much Will All This Cost?

When I totaled it up, the complete course package contains a whopping $657 worth of Python training.

It’s a “one-stop shop” for the dependency management skills and best practices that professional Python engineers are expected to know.

With this course you’re making the smartest kind of investment there is—an investment in yourself and your own abilities as a developer.

And an investment like this could easily pay you back 50X or 100X in the next year.

That might sound over the top, but it’s actually pretty realistic.

Think about it…

The workflows and best practices you’ll get from this course are “table stakes” for senior-level Python development jobs.

Dependency management and application deployment is one of those “icky” but important topics that’s often overlooked by inexperienced developers.

With your newfound skill set you’ll be able to demonstrate that you care about *shipping* a quality product and not “just coding” it.

You’ll be able to help your colleagues with your expertise. Teaching your coworkers new tricks and workflows that make them more productive is the best way to get recognized as an expert.

Pulling everyone else around you UP and making them more productive is a fantastic way to show you’re ready to take on more responsibility—which in turn is one of the best ways to get yourself promoted.

Here’s the kicker:

Even though the “return on investment” for this course is excellent, I wanted it to price it so it is affordable for all Pythonistas in my audience.

That’s why I’m pricing the course at a fair

$49

This offer is for the complete course, including all bonuses.

To put that in perspective, that’s less than what you might pay for a decent keyboard or mouse.

And as an investment in yourself and your development career it will pay off many times over, quickly.

What Pythonistas Are Saying:

“Very informative, thoughtfully approached, and easy to understand”

“I took this course in hopes that I may learn a few things. I already use virtual environments and was familiar with that concept.

I found your course to be very informative, thoughtfully approached, and easy to understand.

You did not leave me behind and, in no part, did I feel lost or confused. In fact, count me in on your next course!

I thought that the presentation as a workflow was very helpful. Nice and sequential.

You answered several questions that I have had, especially with managing the requirements.txt file.

The audio and video quality are really good. The colors chosen contrast nicely which makes reading the bullet points, etc easy while you are talking.

The font size of the presented material in the videos was nice. Your voice cadence and tone were nice. The volume level was good. The length of the videos seemed appropriate. Not so long as to lose attention and not too short so that you wear out your mouse clicking the next video.

When showing the command line in the terminal window, the font size there was nice as well!”

Bill Arbuckle Certified General Appraiser & Pythonista

“A well done, interesting and enjoyable program”

“I thought it a well done, interesting and enjoyable program that provides very usable tips and tricks for people to be better prepared to start developing applications in Python. I’m going after the Sublime Python guide next.”

Jeff M. Network Engineer

“The missing piece I needed to start on my continuous integration project”

“I have used pip ever since starting with Python, but after taking this course, I found that I was not using it as well as I could be.

In the past I had been manually installing 3rd-party modules and always getting the ‘latest’ versions when moving environments or starting new ones, which sometimes caused problems with code - not to mention that I sometimes forgot which modules I needed to install!

With the workflow outlined, I think my programs will become a lot more portable; this was the missing piece I needed to start on my continuous integration project with Jenkins!

Overall this course was full of straight-forward examples and will definitely help me untangle the web that is Python.

Daniel Meyer Sr. Desktop Administrator at Tesla Inc.

“Will move my Python skills to another level”

“I just finished the course. Thanks to you I learned much about the topic. Not all things were completely new, but I clarify most of them and now I feel that I really should use them (and I want to, of course) :) I believe that the acquired knowledge will move my Python skills to another level.”

Tomas Ryba Python Developer

“I found it excellent!”

I have just finished the course. I found it excellent!

On a non-technical note, may I say that you have an excellent ‘manner’ for teaching. Your voice is easy on the ears (I know that may sound daft but some trainers, in my experience, tend to get, or try to be, SUPER EXCITED about everything and it can become somewhat grating after a while) and very clear. You do not speak too slowly, or too fast.

And it’s all beautifully edited and seamless. It just kind of feels like you’re having a nice conversation with a programmer friend who is in the same room with you, sharing his hard-earned experience and knowledge. Outstanding.

I have used venv and pip already but only as a means to an end, so to speak. e.g. I am learning Django at the moment and that introduced me to these tools by necessity. But I’ve only skimmed the surface of them to get to Django, so to speak…

So your course taught me a lot; ready for when I’m doing production projects that actually matter. (I met venv back learning Python itself on Linux - but it was still very useful to go through it again properly.)”

Keith Grant Pythonista at Suitable Software

“Well organized, easy to follow, and full of practical real life examples”

Dan has made an easy to follow course to get the fundamentals right with Python packages and dependency management.

The course also covers the essentials of virtual environments, which are key part of managing dependencies especially on your development environment.

My favorite part is module four where Dan explains his well-defined and practical process, how he finds the quality packages, among the vast number of alternatives, using couple of tools. The module covers several important points, when selecting the right third-party packages for your project. One of the most important ones being licensing, especially if you are building a commercial application. Dan goes through the checks how he identifies the quality of the package in question. He also lays out how to justify your package selection to your colleagues or manager.

Overall, Dan did a great job with the course. The course is well organized, easy to follow, and full of practical real life examples.

I very much recommend this course especially to Python beginners, since this will possibly save a lot of time when getting started with the language and its ecosystem. There’s something new to learn for more seasoned Python developers, too.
