Python: Multiple Exceptions With Parameter

  • submit to reddit
        I had just began to learn python and struggle about the exception handling of python:

class MyExceptionA(Exception):
    def __init__(self, a):
        self.a = a

class MyExceptionB(Exception):
    def __init__(self, a):
        self.a = a

    print('"Do NOT press this button!" ... oh noes!!! ...')
    raise MyExceptionA(42)
#except MyExceptionA, e: # thats the simple one...
#except (MyExceptionA, MyExceptionB): # must use tuple here...
except (MyExceptionA, MyExceptionB), e:
    if vars().has_key('e'): # just for the middle one :D
        print e.a

Its just that I keep that in mind.
