Feedback on Math with Python for Undergraduates

Ian Hawke (who put together these notebooks on testing numerical code) is now putting together some Jupyter Notebooks to teach Python to first-year undergraduates in mathematics. He would be grateful for feedback, and we'd be grateful if you could give him some: we'll learn a lot about what we should teach from seeing what you think he should.

(Note: if you click on one of the .ipynb files in the list on GitHub, the rendered version will be displayed. That's pretty cool.)
