Python 2020: The State of the Language

Presented virtually for Python fwdays 2020 online conference.

The Python language serves many communities: web, science, data science, devops, embedded systems, and education. The talk will discuss what's new in Python 3.8 and the upcoming 3.9 releases. We'll wrap up by discussing how Binder and Jupyter impact in our online world.
