自定义一个java 的UUID to string 是按时间递增的,在写java时,注解随处可见。python的类似注解的方式比较简单deflog(prefix):deflog_decorator(f):defwrapper(*args,**kw):print'[%s]%s()...'%(prefix,f.__name__)returnf(*args,**kw

Python 模块的 uuid4() 函数uuid 生成一个随机的 UUID,而且似乎每次都生成一个不同的: In [1]: import uuid In [2]: uuid.uuid4() Out[2]: UUID('f6c9ad6c-eea0-4049-a7c5-56253bc3e9c0') In [3]: uuid.uuid4() Out[3]: UUID('2fc1b6f9-9052-4564-9be0-777e790af58f') 我希望每...
UUID to String and String to UUID in Python When we call auuid.uuid1or any other version of UUID you will get an instance of UUID class. When we want UUID in string format for comparison, manipulation or maybe for any reason we can get its string representation using a str class. Let...
