Read over your textbook and the notes you took in class -- I'm 
sure therein you'll find how to define functions, how to specify 
parameters, how to return values, and how to do basic arithmetic 
operations.  You can also hit up python.org and 
diveintopython.org for more reading if you need.

I'll give you a hint:  If you use

   twice = lambda x: int(x**2/(0.5*x))

I suspect your professor will flunk you for cheating.
