Python: Testing Sets of Conditions

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.
