I'm surprised this compiles at all for you.  It's
not valid Python syntax; don't you get a syntax error
when trying this out...?

Change the method definition header line to:

    def GetListing(self, thePath, theType):

You need a first argument representing the instance
on which the method is called, and it's common to call
that first argument 'self'.  And no 'str(foo)' in
the arguments' names -- just the names themselves.

If you need to convert an argument to a string, then
do something like
    thePath=str(thePath)
explicitly at the start of the method.
