Just to explain: YBM has tried to sabotage you by posting a
solution that uses a couple of advanced Python features
(lambda and list comprehensions) that a beginner would be
unlikely to know about. The idea is that if you had simply
handed that code in as-is, your teacher would know that you
had almost certainly not written it yourself.
Anyhow, you seem to be almost there. The only thing now
is that your function needs to *return* the result instead
of printing it out. To illustrate with a different example,
you currently have a function like this:
def add(a, b):
print a + b
This is fine as far as it goes, but the drawback is that
printing out the result is all it will ever do. You're
being asked to write a function like this:
def add(a, b):
return a + b
This is much more useful, because you can do anything you
like with the result, e.g.
print add(2, 3) * add(4, 5)
