This is Part 1 of a series of courses intended to dive into the inner mechanics and more complicated aspects of Python 3. This is not a beginner course - if you've been coding Python for a week or a couple of months, you probably should keep writing Python for a bit more before tackling this series.

On the other hand, if you're now starting to ask yourself questions like:

  • I wonder how this works?

  • is there another way of doing this?

  • what's a closure? is that the same as a lambda?

  • I know how to use a decorator someone else wrote, but how does it work? Can I write my own?

  • why isn't this boolean expression returning a boolean value?

  • what does an import actually do, and why am I getting side effects?

  • and similar types of question...

then this course is for you.

Please make sure you review the pre-requisites for this course - although I give a brief refresh of basic concepts at the beginning of the course, those are concepts you should already be very comfortable with as you being this course.

In this course series, I will give you a much more fundamental and deeper understanding of the Python language and the standard library.

Python is called a "batteries-included" language for good reason - there is a ton of functionality in base Python that remains to be explored and studied.

So this course is not about explaining my favorite 3rd party libraries - it's about Python, as a language, and the standard library.

In particular this course is based on the canonical CPython. You will also need Jupyter Notebooks to view the downloadable fully-annotated Python notebooks.

It's about helping you explore Python and answer questions you are asking yourself as you develop more and more with the language.

In Python 3: Deep Dive (Part 1) we will take a much closer look at:

  • Variables - in particular that they are just symbols pointing to objects in memory

  • Namespaces and scope

  • Python's numeric types

  • Python boolean type - there's more to a simple or statement than you might think!

  • Run-time vs compile-time and how that affects function defaults, decorators, importing modules, etc

  • Functions in general (including lambdas)

  • Functional programming techniques (such as map, reduce, filter, zip, etc)

  • Closures

  • Decorators

  • Imports, modules and packages

  • Tuples as data structures

  • Named tuples

To get the most out of this course, you should be prepared to pause the coding videos, and attempt to write code before I do! Sit back during the concept videos, but lean in for the code videos!

And after you have seen a code video, pause the course, and try things out yourself - explore, experiment, play with code, and see how things work (or don't work! - that's also a great way to learn!)

Requirements:
  • Basic introductory knowledge of Python programming (variables, conditional statements, loops, functions, lists, tuples, dictionaries, classes).
  • You will need Python 3.6 or above, and a development environment of your choice (command line, PyCharm, Jupyter, etc.)
Who this course is for:
  • Anyone with a basic understanding of Python that wants to take it to the next level and get a really deep understanding of the Python language and its data structures.
  • Anyone preparing for an in-depth Python technical interview.

What you'll learn:

  • An in-depth look at variables, memory, namespaces and scopes
  • A deep dive into Python's memory management and optimizations
  • In-depth understanding and advanced usage of Python's numerical data types (Booleans, Integers, Floats, Decimals, Fractions, Complex Numbers)
  • Advanced Boolean expressions and operators
  • Advanced usage of callables including functions, lambdas and closures
  • Functional programming techniques such as map, reduce, filter, and partials
  • Create advanced decorators, including parametrized decorators, class decorators, and decorator classes
  • Advanced decorator applications such as memoization and single dispatch generic functions
  • Use and understand Python's complex Module and Package system
  • Idiomatic Python and best practices
  • Understand Python's compile-time and run-time and how this affects your code
  • Avoid common pitfalls

Who teaches Python 3: Deep Dive (Part 1 - Functional)? Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.

Frequently asked questions

What are the prerequisites for enrolling in this course?
This course is not designed for beginners. Prospective students should have experience coding in Python for at least a few months. Familiarity with basic concepts such as loops, functions, classes, and conditionals is expected to fully grasp the more advanced topics covered.
What specific topics are covered in this course?
The course covers advanced topics in Python 3, focusing on functional aspects. Key lessons include Python's type hierarchy, memory management through reference counting and garbage collection, variable mutability, Python optimizations like interning and peephole, and detailed exploration of data types such as integers, floats, decimals, and complex numbers.
Who is the target audience for this course?
The course is intended for intermediate to advanced Python users who have a foundational understanding of the language and seek to deepen their knowledge of Python's functional and internal mechanics. It is particularly suited for developers interested in exploring Python's more complex features and optimizations.
How does the depth of this course compare to other Python courses?
This course dives into the intricate details of Python 3, such as memory references, object mutability, and internal optimizations. Unlike many introductory or general Python courses, it focuses on the inner workings of Python, making it more suitable for those who wish to understand the language beyond surface-level syntax and functionality.
What tools or platforms are specifically covered in the course?
The course does not focus on specific external tools or platforms but rather on Python's internal mechanisms and data type handling. It provides insights into Python's memory management, optimizations, and data type operations, which are crucial for writing efficient Python code.
What is not covered in this course that I might need to learn separately?
This course does not cover introductory Python programming concepts, web development frameworks, or Python libraries like NumPy or pandas. It also does not address Python GUI frameworks or deployment strategies. Students may need to explore these topics separately if they are relevant to their goals.
How much time should I expect to dedicate to this course?
While the total runtime of the course is not specified, students should be prepared for an intensive study due to the advanced and detailed nature of the topics. With 158 lessons, substantial time will be required for both watching the lectures and practicing the coding exercises to ensure thorough understanding.
