This example [1] assumes you are using a specific platform to check it out. I am using amd64, and I get different results. To fix, I prefix the format string with '>': before: pack('hhl', 1, 2, 3) after: pack('>hhl', 1, 2, 3) 1: http://hg.python.org/cpython/file/d3ddbad31b3e/Doc/library/struct.rst#l299

And the examples make an explicit note of that: """ .. note:: All examples assume a native byte order, size, and alignment with a big-endian machine. """ AMD64 is little-endian; the examples are noted to be in big-endian. Is that note not sufficient?

Sadly, I noticed it only after submitting this report.
