You should be able to create PyLong objects from your 64 bit integers. PyLong objects have unlimited integer precision. Alas I don't know enough about the internal C code of Python to know what function to use to do the conversion from an int64 to a PyLong object. -- http://mail.python.org/mailman/listinfo/python-list
