I think this lecture by David J. Malan of Harvard, introducing Python in Week 8, having slogged through C already, is top notch. He's using Python 3 and really covering a ton of material, with lots of references back to the C lectures. This is the only lecture of the series I've seen at this point. He somewhat reveals has Perl background (a lineage he confesses to) in treating a module so much like a class, to where he starts calling functions methods just because their imported and belong to some module. In Perl, entire modules got blessed as classes as I recall. On the topic of 'if __name__ == "__main__"', he's quite good on that but seems to tie it to calling a function called main() every time. I prefer to explain that module may in principal be the one running top-level, with everything else imported. When imported, a module is never "__main__" by default, so here's a way to provide a "just in case" section, containing whatever. He's good on Python being a both a language and a machine to combines compiling and running into a single step, with bytecode the intermediate runtime language. He didn't stop to talk about the different versions of Python in the sense of CPython, Jython, Iron Python and PyPy. I thought he would. Maybe in Week 9. Within one two hour episode he's taken us all the way from simple assignment and string formatting, to writing a simple Flask application complete with Jinja2. As someone who has lectured on Python quite a bit, I have to admire the guy's stamina and sustained coherence. Kirby PS: along those lines, I've been pumping out a bunch of Youtubes recently, two of which feature repl.it using Python. My scripts are somewhat trivial this time, whereas in past Youtubes I've been showing off fancy VPython: https://www.youtube.com/playlist?list=PLeBIlkJm4xglicSifacG4eewD9CQaWvU0 It'll suggest you log in / create account but you don't have to.
