I notice this is homework so I won't give a direct answer.
But look at the mod operator '%'  - It returns the remainder
of an integer division. An even number is exactly divisible
by 2.

Thats a terrible way to convert to a float. Just use the float 
function
(actually a type):

f = float(anInt)

But to determine if its odd/even you don't need to use floats at all.

Hmm, I have no idea what this is doing...
