Introduction to Bitwise Operators

A BIT of This AND That

The bitwise AND (`&`

) operator compares two numbers on a bit level and returns a number where the bits of that number are turned on if the corresponding bits of **both** numbers are 1. For example:

a: 00101010 42 b: 00001111 15 =================== a & b: 00001010 10

As you can see, the 2’s bit and the 8’s bit are the only bits that are on in both `a`

and `b`

, so `a & b`

only contains those bits. Note that using the `&`

operator can only result in a number that is less than or equal to the smaller of the two values.

So remember, for every given bit in `a`

and `b`

:

0 & 0 = 0 0 & 1 = 0 1 & 0 = 0 1 & 1 = 1

Therefore,

0b111 (7) & 0b1010 (10) = 0b10

which equals two.

### Instructions

**1.**

`print`

out the result of calling `bin()`

on `0b1110 & 0b101`

.

See if you can guess what the output will be!
