PYC and PYO files contain bytecode, and are not guaranteed to be portable between different 2.X releases. to check the bytecode revision used by a given Python interpreter, you can use imp.get_magic(): Python 2.3.5 >>> import imp >>> imp.get_magic() ';\xf2\r\n' Python 2.4.1 >>> import imp >>> imp.get_magic() 'm\xf2\r\n' </F> _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
