what does it mean in python: i&1

Question

Please, help to understand instruction

Answer 1

with 7 111&101 = 101 or 5, with 8 or 1000&0101 = 0000 or 0

Answer 2

it is binary "and".

Eg 7 = 111

111 and
001

= 1

Actually it is a test if a number i is odd.
if yes, the result is 1.

Answer 3

& is the bit and operator. i&1 is 0 for even numbers and 1 for odd. if i is 5, 101&001=001 as that is the only bit that is 1 in both numbers.

Answer 4

Thank you. And what is i&5, for example?
