The AND operator is represented by an & (ampersand) symbol in Python. It compares two bits and returns 1 if and only if both the operands are 1. If either one of the operands is 0, then the operator will return a 0.
We can see what happens when we do 5 & 4 below:
As you can see the answer is 4. The image below explains why this occurred.
The image above displays the and operation between the bits of 5 and 4. As we can see in the resulting bits in the bottom row, only the third bit from the right is 1. As per the and operation when both operands that are 1, the result is 1. The first bit from the right results as 0 as only one of the operands is 1.
