Give a function like this:

def fun(x,y): return x / y;

The following statement would produce an error at runtime (ie. a "propgram crash"):

print( fun(2, 0) )

Instead of simply "crashing", show an altered version of the fun function that would return Python's None type if division-by-zero is attempted or some other error occurs in the function. (Of course, it should still return the correct answer otherwise.)
