python模块uuid产生唯一id

 

使用版本4：uuid4就可以了

UUID4缺点：糟糕的随机数发生器使得它更有可能发生碰撞，但是概率真的很小

UUID1缺点：暴露隐私

 

If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer’s network address. uuid4()creates a random UUID.
