Well, you could write them yourself?
[untested]
def set_bit(i, n):
return i | (1 << n)
def unset_bit(i, n):
return i & ~(1 << n)
def test_bit(i, n):
return i & (1 << n)
Note that integers are immutable, so there's no way to change an existing int.
Also, if you're playing with stuff at that level, you might find the
struct module helpful.
