Recitation 3 has a great run down on tuples, lists and dictionaries with examples. But the video often didn't do close ups of the data show, and when it did it was often out of focus. Is there a pdf or file available for Recitation 3?
I didn't see a pdf for the recitation. But, down towards the bottom of the page there's additional resources that cover a lot of the same material quite well. Further Study These optional resources are provided for students that wish to explore this topic more fully. Readings After watching the lecture, you may want to read some of the following resources: 4.9 Recursion. How to Think Like a Computer Scientist. Recursion. An Introduction to Python. Comparing Recursion and Looping. An Introduction to Python.
