In daily life, random numbers are actually often encountered, want to throw dice, lottery, and draw lots. Oh, very simple can be achieved. So in doing programming, really to design a random number through their own program that is really not easy.

The UUID module is introduced after Python 2.5, which includes: Immutable object UUID (UUID Class) and Functions Uuid1 (), UUID3 (), Uuid4 (), and UUID5 (), followed by four functions for generating 1th, 3, 4, specified in the RFC 4122 specification

  GUID is a 128-bit long number, which is generally expressed in hexadecimal notation.AlgorithmThe core idea is to combine the machine's Nic, local time, and a random number to generate a guid. Theoretically, if a machine generates 10000000
