Python Cram School 102

Be Prepared!

If you don't have Python and VSCode installed, visit my Teaching Python page. While there, do these two things.

1. View Corey Schaefer's video and install the current version of Python on your lappy. He has complete instructions for all platforms. If you see a box to check to update your environment variables, check it! View this video to the end; he shows you how to test your install and gives you a little introduction to the language.
2. Install VSCode; you will see a link with instructions for installing it and configuring it for Python on both a Mac and a Windoze machine.

Cram School 101 is a prerequisite!

We pick up where 101 leaves off. You will have full procedural Turing-complete powers when you finish this workshop.

• Python Collections:
  • str a protean sequence type
  • list a mutable sequence type
  • tuple an immutable sequence type
  • mutablity: It's convenient and dangerous!
  • hashablity: The key to rapid insertion and retrieval in the next two data structures
  • set yer in or you ain't
  • dict A collection of key-value pairs
• Iterables, Iterators, and Iteration
• Iterables: things that can be walked through
• Iterators: things that do the walking and then die
• Iteration: the process of walking
• Comprehensions: When you go out to eat, stay out of the kitchen!
• Python FileIO and the with boss statement
