[Python Edinburgh] Pub Meetup Tomorrow: Who's Coming?

[Mark Smith]

Great to hear that you're coming.

I haven't tested the following, but maybe it helps?

def check_bit(bit, value):
    mask == 0x1 >> bit
    return (value & mask) == mask

if check_bit(3, y) and not check_bit(0, y):
    print 'yay!'
