Here is the next script of Python you will enter, which introduces you to the if-statement. Type this in, make it run exactly right, and then we'll try see if your practice has paid off.
people = 20 cats = 30 dogs = 15 if people < cats: print "Too many cats! The world is doomed!" if people > cats: print "Not many cats! The world is saved!" if people < dogs: print "The world is drooled on!" if people > dogs: print "The world is dry!" dogs += 5 if people >= dogs: print "People are greater than or equal to dogs." if people <= dogs: print "People are less than or equal to dogs." if people == dogs: print "People are dogs."
In this extra credit, try to guess what you think the if-statement is and what it does. Try to answer these questions in your own words before moving onto the next exercise:
