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

So, when I print this out, it doesn't print out 6, even though the range is 0 to 6. Why not?
