Hello,
bitset is not a Python module. It is now in sage.data_structures and
not anymore in sage.misc (since 6.3.beta4, see
http://trac.sagemath.org/ticket/17196). The following works for me
sage: from sage.data_structures.bitset import FrozenBitset, Bitset
sage: Bitset
sage: FrozenBitset
What
The python used by sage is not the system python. So you should do
./sage -sh
in SAGE_ROOT and then try “python -m bitset”
