Advanced Python objects

Go beyond simple classes and methods. Understand and use everything Python's objects have to offer.

Take your Python objects to the next level.

Already know how to write Python classes and methods? Then you're ready to dig into Python's object-oriented capabilities, striking at the heart of the language.

In this course, I teach you all about Python's objects, going deeper than most courses. In particular, I show you:
  • The many "magic methods" that you can write, including for operator overloading
  • The context manager protocol, and how you use make your objects behave in a "with" statement
  • How to write and use properties
  • The descriptor protocol, and how it explains how methods differ from functions
  • Metaclasses — what they are, and how to (and not to) use them
I walk you through all of this in more than hours of video, spread across 75 separate videos. I also ensure that you check your knowledge with numerous exercises.

If you want to take your Python to the next level, doing more with less code, then this course is for you.

What people say about "Advanced Python objects"

This is by far the most amazing Python course I have taken. It is full 
of advanced information, especially for people who want to take 
their Python skills to next level.

FAQs

Who should take this course?

This course is aimed at developers with experience writing Python classes, typically for a year or so. If you've taken my "Object-oriented Python" course and have then used those ideas in your development for a few months, then you're probably ready for this course.

What version of Python do you use?

3.7, although I do briefly mention a new feature in 3.8.  (I didn't have 3.8 running on my computer when producing the course.)  

If you have Python 3.6 or above,then you're fine for this course.

Is there a “trial” version or sample?

No, but (a) you can view a number of the videos for free, without purchasing the course, and (b) I offer a 100% guaranteed refund if you need.  

Is automated testing a part of this course?

No, but I am preparing a separate course on "pytest" that will cover functions (among other topics).

I live in Israel. How do you handle issues like VAT?

If you live in Israel, then please don't buy any of my products (including Weekly Python Exercise) via this online platform. I'm obligated to collect VAT from you, and then to pass it along to the government.  Instead, please e-mail me for information about sending me a bank transfer. I'll then add you to the course, but we'll be able to handle it in the standard and legal way. I apologize for this frustration -- believe me, I wish that the platform I use for selling courses would support Israeli VAT, and I keep asking them to do so.

What if I find that the course is too easy or hard, or that I just dislike your jokes?

If you aren't satisfied with my course, then I'll refund your money.  Just e-mail me.  I believe that I'm offering a high-quality product, but I also know that it's not for everyone.

As for the jokes, people have been trying to help me for years. So far, my jokes have just gotten worse, not better. Oh, well.

Do you offer any discounts?

Yes, I offer discounts for students, pensioners/retirees, and anyone living outside of the world's 30 richest countries. E-mail me at reuven@lerner.co.il for an appropriate coupon code.

I have other questions. What should I do?
