Master Python objects (and understand how they work)

I’ve been teaching Python for many years now, and it never ceases to amaze me to discover just how many people are able to use Python without ever having really learned it.

In particular, there are lots of people writing and using Python objects who assume that classes and instances in Python work just like those in Java and C#, but with less syntax.

For the most part, they can make those assumptions and not suffer too much.  But then, if something goes wrong… well, they’re at a loss to explain how and why things didn’t work.

And then little things nag them: Why does “self” need to be the first parameter in a method? And when we set a variable inside of a class definition, are we setting the default for the instances? (Answer: No, because you’re setting a class attribute.)  How does inheritance really work?  And how does super() work in Python?

Knowing the answers to these and other questions are the key to becoming a more fluent Python developer. That’s important, because fluency will allow you to do more in less time, to write more expressive and powerful code, and to write code that can be changed and maintained more easily.

I’ve taken my lessons and exercises from my intro Python class and turned them into a new online class, “Object oriented Python.”  The course assumes that you’re familiar with basic Python data structures and functions, but otherwise starts with the basics of object-oriented programming, through inheritance and operator overloading.

In more than 4 hours of video lectures, and with 15 exercises, I walk you through how Python’s object system works, and how you can make it work for you.

This course is for you if:

  • You’re a Python developer unfamiliar with objects
  • You’ve been cutting, pasting, and editing Python code for years from Stack Overflow and blogs, without really understanding how objects work
  • You’re new to Python, but experienced with objects in another language, such as C#, C++, or Java

This is the same material I teach at companies like Apple, Cisco, IBM, Intel, PayPal, Western Digital, and VMWare.  I’m booked solid 8 months in advance with training at these companies  — but you can get these lessons, and improve your Python coding, in the coming minutes.

The course includes:

  • More than four hours of lecture/screencasts
  • 15 exercises, including extensive walk-throughs of the solutions
  • PDFs of the slides I use when teaching about objects
  • The Jupyter notebook I used when live-coding the course
  • Any and all updates I make to this course in the future, via my “forever free” policy

Also: You get access to my online office hours, given every 3-4 weeks, online, to students in all of my classes.  Come and ask your Python questions!  Or submit them, and I’ll answer them for you in video.

Not sure?  Go to the course page; a number of the lessons are available for free preview.
