But the x>  10 is never checked.

Must I use two try except now ?
Your first problem has nothing to do with exception handling.
The culprit is Line 4:
                x = int(x) and x>  0
I suppose that you forgot a second equal sign between x and int(x). If 
it were
               x == int(x) and x > 0
it would have worked as expected. But this would not trigger any 
exception, if X is a number. So let's add one:
>                if not (x == int(x) and x > 0): raise(ValueError)

Hope that helps,
