The above generator, throws '*ZeroDivisionError*' exception if ListA[i]
=
0.
Is there a way to say 'Don't divide by ListA[i] if its equal to 0 (within
that statement)'.
You could use an 'or' sideffect
result = [(ListA[i] - ListB[i-1])/(ListA[i] or 1) for i in
range(len(ListA))]
But whether dividing by 1 as a default makes any sense will be a
choice depending on the application and data.
