Python 3.11: A Guided Tour Through Code Course

This course is carbon neutral.

Course Summary

Python 3.11 is one of the most significant releases in years. It's also one of the biggest with the change log weighing in at over 175,000 words of updates. You may have seen the headline features.

What students are saying

Let me say that your courses are tremendous and I am a huge fan. I had tried a few different online learning platforms (edx, datacamp), so when I found your Python Jumpstart, I decided to finally give a paid course a try. Your courses strike an excellent balance between hand-holding and DIY, and they suit my learning style perfectly. [...] I'm a lifetime customer. Thank you for the great content, I appreciate the work you're doing.

Who is this course for?

For anyone who wants to take advantage of the latest Python features. In this course we focus on Python 3.11's new features of course. But in doing so, we tie them back to many of modern Python's latest idioms and capabilities.

As for prerequisites, we assume:

  • Basic familiarity with the Python programming language and core tools (e.g. pip)

The tools chosen and featured during this course are 100% free and most of them are open source.

Concepts backed by concise visuals

While exploring a topic interactively with demos and live code is very engaging, it can lose the forest for the trees. That's why when we hit a new topic, we stop and discuss it with concise and clear visuals.

Here's a graph showing Python 3.10 vs. Python 3.11 performance on the pypi.org web app.
