You print inside your function (print x, "is odd") and you print the
result of your function (print funcA(x)). As your function doesn't
explicitly return a value, you get None, see:
http://www.python.org/doc/2.4.2/tut/node6.html#SECTION006600000000000000000
So either just call the function or return the string from your function.
