You should probably stop your function here by returning names.
for each in names:
print "Hurray for", each +"!"
print
It's good practice to keep the presentation logic outside
the function. Your loop would then change to
for each in getNames():

However I cannot use the len() built in function. The Teacher is asking
for another solution that does not use the len() t
That's bizarre. It forces you to write a bad solution.
However, Mark has already given you the necessary hint.
But using len() is absolutely the sane way to do this
(unless you are paranoid about micro performance).
