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 list
for number in the_count:
  print "This is count %d" % number
# same as above
for 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 it
for i in change:
  print "I got %r" % i
# we can also build lists, first start with an empty one
elements = []
# then use the range function to do 0 to 5 counts
for 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 too
for i in elements:
  print "Element was: %d" % i
