Ah, now things make sense! Your subject line is misleading! It's not that
the wikibooks example doesn't work, the example works fine. It's that the
code you added to it doesn't do what you expected. You should have said.

You don't check the counter until after the loop has finished. It needs to
be inside the loop, not outside:

while looping:
    # See the indent?
    # this is inside the loop

# No indent.
# This is outside the loop.


Also, having reached the count of three, you will want to break out of the
loop. The "break" command does that.

Is this enough of a hint to continue? Please feel free to ask any further
questions you need.
