I am trying to reduce the amount of time taken to implement a fucntion

def findAns(a, b, c):

    return (a&b)*(b&c)

What interpretation can I make based on the nature of bitwise AND other than the normal gate based interpretation? What does it actually do?

(1) No, it is not distributive. (2) Just that: a bitwise AND - unless your objects are not numbers but classes with redefined `__and__`. (3) If bitwise performance becomes an issue, it may be time to say goodbye to Python and switch to C++/C. – DYZ May 01 '20 at 23:17
