Exercise 32: Loops And Lists

the_count = [1, 2, 3, 4, 5]fruits = [apples, oranges, pears, apricots]change = [1, pennies, 2, dimes, 3, quarters]# this first kind of for-loop goes through a listfor number in the_count:  print "This is count %d" % number# same as abovefor fruit in fruits:  print "A fruit of type: %s" % fruit# also we can go through mixed lists too# notice we have to use %r since we don‘t know what‘s in itfor i in change:  print "I got %r" % i# we can also build lists, first start with an empty oneelements = []# then use the range function to do 0 to 5 countsfor i in range(0, 6):  print "Adding %d to the list." % i # append is a function that lists understand  elements.append(i)# now we can print them out toofor i in elements:  print "Element was: %d" % i
