'and' is logical operator. If both operands are non-zero then 'and' will return 1 else 0. It is equivalent to && operator.

& is bitwise operator. Example

and keyword is an alternative of logical-and (&&) and not bitwise-and (&)

and — logic operator ( 2 and 3) = (true and true) = true = 1

& — bit operator (2 & 3) = binary(10 & 11) = binary(10) = 2
