Exercise 5: More Variables and Printing

Now we'll do even more typing of variables and printing them out. This time we'll use something called a "format string." Every time you put " (double-quotes) around a piece of text you have been making a string. A string is how you make something that your program might give to a human. You print strings, save strings to files, send strings to web servers, and many other things.

my_name = 'Zed A. Shaw'

my_age = 35 # not a lie

my_height = 74 # inches

my_weight = 180 # lbs

my_eyes = 'Blue'

my_teeth = 'White'

my_hair = 'Brown'

print ("Let's talk about %s." % my_name)

print ("He's %d inches tall." % my_height)

print ("He's %d pounds heavy." % my_weight)

print ("Actually that's not too heavy.")

print ("He's got %s eyes and %s hair." % (my_eyes, my_hair))

print ("His teeth are usually %s depending on the coffee." % my_teeth)

# this line is tricky, try to get it exactly right

print ("If I add %d, %d, and %d I get %d." % (

    my_age, my_height, my_weight, my_age + my_height + my_weight))
