Title: Learn to use bitwise AND &.

Not the knowledge point, checked the bitwise operation.

A bitwise operator computes a number as a binary.

operator Description Example
& Bitwise AND Operator: Two values that participate in the operation, if two corresponding bits are 1, the result of that bit is 1, otherwise 0 (A & B) Output result 12, binary interpretation: 0000 1100
| Bitwise OR operator: As long as the corresponding two binary has one for 1 o'clock, the result bit is 1. (A | b) output result 61, Binary interpretation: 0011 1101
^ Bitwise XOR Operator: When two corresponding binary differences, the result is 1 (a ^ b) output result 49, binary interpretation: 0011 0001
~ Bitwise inverse operator: each bits of the data is reversed, that is, 1 is changed to 0, and 0 to 1. ~x similar to -x-1 (~a) Output result-61, Binary interpretation: 1100 0011, in the complement form of a signed binary number.

The representation of a Python binary:

• Binary: 0b
• Octal: 0o
• 16 Binary: 0x

Conversion of the binary:

Binary: Bin ()

Octal: Oct ()

Hex: Hex ()

The direct output is the decimal.
