Hello,
first question
In [117]: cmp("ABC",['A','B','C'])
Out[117]: 1
against what part of the list is the string "ABC" compared?
second question
In [119]: class X(object):
.: pass
.:
In [120]: X() < X()
Out[120]: True
In [121]: X() < X()
Out[121]: False
In [122]: X() < X

Problem solved.
Turns out it was a problem of mistranslating VBS code to Python.
The PYTHON line "print str(tet)" casts tet to a string and prints. This
is what I thought the VBS line "Str = Tet.ConvertToString()" was doing.
But of course "ConvertToString()" is a method of a Tet instance. So in
