Go to Chapter 20 of A Smarter Way.
A tuple is like a list, but its elements cannot be changed once they’re defined.
In a list we used square brackets to define the list:
friends = ['bill', 'jeff', 'jim', 'scott', 'joel']
By contrast, in a tuple we use parens (parentheses):
colors = ('red', 'green', 'blue')
We use tuples in situations like printing out a series of values.
animals = ('armadillo', 'squirrel', 'cat') for animal in animals: print("Don't run over the " + animal + ".")
