Overview

In this class, we’ll be using the programming language called Python to tell the computer what we want it to do. Today will be focused on getting some basic definitions and functionality in Python figured out.

Basic Learning Objectives

Before class, you should be able to:

  • Explain what comments in programming are
  • Give examples of at least two values of different types in Python
  • Use a built-in/provided function
  • Define the term variable in a programming context
  • Make a new variable using an assignment statement
  • Use an existing variable

Advanced Learning Objectives

After class, you should be able to:

  • Create and run a program using VSCode
  • Submit programs to Gradescope
  • Edit programs based on Gradescope feedback
  • Use pair programming to write a program
  • Predict what type an expression will result in
  • Explain how int and float values interact
  • Explain what it means to evaluate a variable and identify when evaluation occurs

Readings

You should complete the following Runestone readings and the embedded checks (it looks like a lot, but many of the sections are short):

Checks

Submit answers to the following on Moodle.

  • Write a program that will compute the area of a circle (which is the radius squared, multiplied by pi (3.14)). Have the program work regardless of what value the radius variable is set to. Print a nice message back to the user with the answer. Be sure to copy what you write below and save it in Moodle.
  • You should also try to join the class’ Gradescope so that you are ready for the in-class lab
