So for a True result when arg%2 is zero, you must negate the logic

Outcome = (t-32)/1.8

>or a number
Assuming t is a number the outcome will be a number so it should work.
It helps if you cut n paste the real code and the real error message,
do not just summarise. Python error messages are extremely helpful,
but only if we can see them.
