From an educator's perspective, how to best phase-in Python is often a core
question.
One answer is: use it the same way you might use a calculator in the
classroom, but show off why it's better.
An example (new today) of what I share with my student and peer faculty,
perhaps new to Python:

A mix of Python + geometric content already familiar to those using my
curriculum.
The docstring itself contains a link to the famous Using Python as a
Calculator tutorial at the Python dot org site.
