Why no ZeroDivisionError?

Short answer. The left side is False, so Python skips the right.

When does or stop early?

When the left side is True.

Remember

and: False on left, stop
or: True on left, stop

This divides by zero. Why no crash? Bal is the balance. And needs both sides True. The left is False, so Python skips the right. That is short circuit. With and, a False left stops it. With or, a True left stops it.
