 A few words about the videos in this course. Most of them will be fairly short, and they'll investigate one or two concepts each. Some of them will be a little bit longer, and those are the ones usually where I'm developing an entire program. Some of the videos are very highly scripted, and others, like this one, are more performance art as I make things up as I go along. So don't be surprised if there's some difference in those two areas. I do edit these videos to get rid of some of the major errors. So if you see a screen change dramatically from one frame to another, you'll know I did some editing. Most of the time, if it's just a minor error, I'll just keep plowing right along, so bear with me on that. That's what you need to know about the videos in this course, and let's start learning Python.
