Follow-Me videos:

For module m1f_expressions: Video [49:42]
- This video has an associated quiz in Moodle.
- Contrary to what the video says, you have already put the Session 2 starting code into PyCharm, per the directions to the left. Ignore what the video says about Update Project.
- This video introduces a lot of ideas, almost all of which will be so natural to you that you hardly need to be told it. As you watch the video and do the accompanying work in PyCharm, make notes to yourself on things that you think you might not remember until you have practiced them more. Over the next few sessions, you will get LOTS of practice on ALL the ideas in this video.
- In making this video, we spoke and typed slowly, so that you could keep up with the video. For some of you, it may be TOO slow; if so, watch it at 1.5 (or even double) speed, using the settings that YouTube provides in most browsers.
For module m2f_calling_functions_and_methods: Video [19:43]
