I just rewrote this, It's now giving me a F: prompt but then
I'm using 3.1 in Ubuntu

You're trying to subtract an integer from a string. You need to convert the input to an integer.

F = int(input("F: "))

I ran a debuger and F is getting the equation correct. The thing is this script runs in 2.6, but not in 3.1 in 3.1 it always get hung on the last " oh and I can't import os os.sys('cls') on 2.1 so yeah, it's really messed up!

It gets hung on which "?

I ran this code on ideone's python 3 (with some modification) and it worked.

import os

import sys

happy = "sit"

while happy == "sit":

    os.system('clear')

    try:

        F = int(input("F: "))

    except KeyboardInterrupt:

        print ("Goodbye!")

        sys.exit()

    except:

        F = 0

    CEL = (F - 32) * 5 / 9

    print ("C:", CEL)
