Talk Python - Python 3.11: A Guided Tour Through Code Course

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. But have you had a chance to explore them with code and really see how they can make your apps better? This 2-hour course is your guided tour of the changes to Python with this important release.

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.
