I would think the simplest way to handle this would be to add an additional condition inside your pre-existing condition (that is not related to Obama Care ) to test if "n2" is 0 (zero) before you attempt to divide by it:
e.g.
If the intention is not to show that you are dividing by zero, but to prevent it doing so altogether, you can amend the existing elif that handles that case to also check that "n2" is not zero. Talking of which, it may be better (simpler) to use a "case" statement instead of "if" - ifs can get a bit clumsy looking, when there's lots of elifs going on.
