@craigmaloney Python is convenient for all kinds of things, isn't it? I learned it to teach a class (Numerical Analysis) and didn't want to have to learn Java (which all our students have to learn). Now most of our math majors get a couple of computer languages. I hope to find time to learn it better. Just in case you haven't done this and don't know it: Type "import antigravity" into Python. (If you already know, never mind.)
