While being able to program the TI series of calculators has been around for awhile, being able to program in Python is very cool. There have been posts in the past about the viability of Python, for TI to put a big chunk of their business on it is great. This should have a cross benefit of making more roboteers and just math people fluent.
And you can try out your new PID code in math class since you are just “using your calculator”
I use the TI-Nspire™ App for iPad® - US and Canada on my iPad, wonder if they will upgrade it with Python too?
