[Tutor] introspecting exceptions?

[Marilyn Davis]

Hello Python Experts,

I'm looking for a way to introspect exceptions.

dir() gives, amongst other things, a list of exceptions.

I can do these things:

>>> ZeroDivisionError.__doc__
'Second argument to a division or modulo operation was zero.'
>>> dir(ZeroDivisionError)
['__doc__', '__getitem__', '__init__', '__module__', '__str__']
>>> ZeroDivisionError.__module__
'exceptions'
>>> exceptions.__doc__
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'exceptions' is not defined
>>> 

I'm hoping to find the hierarchy of exceptions somehow.

Thank you in advance.
