The double float conversion looks wonky but wouldn't be the cause. You shouldn't need to do
degf2 = float(float(f.read())) You should be able to do degf2 = float(f.read()) The error message in your email says what the problem is - you're getting 94.8\x00 as the string and it's failing to convert it to a float. Not sure why your try catch doesn't work. I'd like to see what Gary's asking for - put the try/catch in let's see the output.
