    >>> a = 1/0 or 100
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ZeroDivisionError: division by zero
    >>> a
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    NameError: name 'a' is not defined
    >>> a = 0/1 or 100
    >>> a
    100
    >>>
