The Python equivalents of these methods are described in the reference manual: http://docs.python.org/ref/numeric-types.html More details can be founf in various PEPs: http://www.python.org/dev/peps/ > Does Python use classic division (nb_divide) and inversion (nb_invert) > or are they entirely historical? Note that I can very easily provide > the latter. Python uses classic divison by default. True divison is used only when the division __future__ directive is in effect. See PEP 238 for details: http://www.python.org/dev/peps/pep-0238/ The nb_invert method is used for the implementation of the bitwise inverse unary operator (~). I don't think that it is deprecated. See: http://docs.python.org/lib/bitstring-ops.html for details. > Is there any documentation on the coercion function (nb_coerce)? It > seems to have unusual properties. It is used for old style Python classes and extension types that don't have Py_TPFLAGS_CHECKTYPES in their tp_flags. See: http://docs.python.org/ref/coercion-rules.html and http://www.python.org/dev/peps/pep-0208/ for details. Ziga -- http://mail.python.org/mailman/listinfo/python-list
