Go to Chapter 12 of A Smarter Way.

What do you do if a test needs to meet two conditions at once? (Is this person both a Person and a Friend?)

This is where the keywords and and or come into play.

if student_count > 10 and chairs_count <= 10:
    print("Somebody's going to be standing.")

You can use more than one and orĀ or in the test:

if (doughnuts == 12 or crullers == 12)and coworkers_count <= 12:
    print("Everybody gets a goodie.")

Use parens to establish order of operations.

  1. Continue editing examples.py.
  2. Create one example of a single and test, and one example of a single or test.
  3. Create one example of a test that involves more than one and or or.
