All Python objects start (at C level) with a header (containing
the reference count, a pointer to the associated type and
maybe other things); the "real" value starts behind this header.

This means, to see the "1" in your example, you must skip the
associated object header -- either in the output or by adding
the size of the header to the initial address.
