Furthermore, it's almost never the case that you legitimately expect to divide by zero. In the case of Python where exception handling is pervasive and idiomatic, it's far more reasonable to treat that as, well, an exception. If you're doing an operation that sometimes execute divide-by-zero, you can watch out for it and handle it appropriately. When you're not expecting to be doing that calculation, it's an error.
