Canvas Quiz of the Day (need daily password)

Most days, there will be a simple canvas quiz related to the lecture. You need a password to activate the quiz, which I will provide in class. These quizzes will count toward your class participation grade. The quiz is available only during class.

Click for today's quiz.

Note: the collaboration quiz is separate. It coincides with the first homework assignment.

Lecture 1: Python.

Administrivia

  • I have office hours Wednesdays from 4-6 pm, on zoom, id 459 434 2854.

  • In the coming weeks, I will be available for lunch on Mondays at 1 pm in Morse. Stay tuned.

  • ULA office hours are found at Ed Discussions on Canvas

  • Homework assignments: [Assignments]. hw0 is now available. Note: I will list provisional due dates for all assignments. The name of your homework file submitted to gradescope must be exactly the same as the assignment file, e.g., hw0.py, hw1.py. Otherwise, zippo.

    If you're thinking of taking CPSC 2000, please do the following.

  • Complete this online Student Information form.
  • Get a course account for CPSC 2000 on the Zoo. When you register for this class, your course account should be created within one hour or so of signing up.
  • Start the reading assignment: [Assignments]. Demo hw0.py (hw0a.pyc)
  • Familiarize yourself with the Zoo computers on your own using the Zoo tutorial, Spring 2014 edition.
  • (Optional.) Download and install Python on your computer (Python) and familiarize yourself with it. If you don't want to install and run Python on your machine, you may run it in person or remotely using your Zoo account.

    Note that there are two current versions of Python: 2 and 3, which are not quite compatible. We suggest that you opt for version 3.

    Announcements

  • Poorvu STEM Navigators Program.

    Clarity

    Yale provides free access to three large language models: OpenAI's ChatGPT, Anthropic's Claude, and Google's Gemini. See Clarity. I suggest that use these models as a study aid, e.g., to come up with sample exam practice questions.

    Collatz Conjecture

    Want to win a Fields Medal? Solve the Collatz Conjecture! (aka, Kakutani's Problem).

    We define a function collatz(n) (where n is an arbitrary positive integer) which behaves as follows:

    Next, let's define a sequence of Collatz numbers, such that the output of each call becomes the input of the next, unless and until you arrive at 1. The conjecture part is to prove that this series will always converge to 1.

    We now turn to some python code that implements Collatz collatz.py
