[Zope] Help using list within python method

[Michael Long]

I have a method that is returning an error that I have not been able to
resolve. I have tried to duplicate the error in python to no avail. I am
sure the solution is very simple I just don't see it.

tia,
Mike

 Here is the method:

    172         def listEntriesByGroup(self, groups=["All"]):
    173                 "Method to list Entries"
    174                 ret=[]
    175                 if type(groups) != ListType:
    176                         EntryIDs = [groups]
    177                 if groups == "All":
    178                         for entry in self.Entries.values():
    179                                 ret.append(entry)
    180                 else:
    181                         for entry in self.Entries.values():
    182                                 if entry.Group in groups:
    183                                         ret.append(entry)
    184                 return ret

The traceback is:
