If you're looking for similar names in use, PyPI has (at least) modules named bitsets, bitset, bitmap, bitstring, bitarray, and flags, which are all related to what's being discussed here, but crucially without the enum-like naming of the bits.

(I've used bitstring and bitarray for things like examining the bits of a TCP header; the others I just saw when searching for bitarray when I couldn't remember its name...)
