验证者给定一个随机字符串s,工作者必须找出一个数n,使得随机字符串拼上这个数n后的md5结果前面几位都是0. 即md5(s+n)的结果符合验证者的要求.工作者仅仅能不停的穷举,找出这样一个数n. 以下上python代码. 工作方: #coding=utf-8 from itertools import count from hashlib import md5 msg = 'randomstring...
python中proofpython中proof的用法 Python内置的@property装饰器可以把类的方法伪装成属性调用的方式。也就是本来是Foo.func()的调用方法,变成Foo.func的方式。在很多场合下,这是一种非常有用的机制。class People: def __init__(self, name, age): self.__name = name self.__age = age ...

What keeps Python from being truly fast? One of the most common answers is “lack of a better way to execute code across multiple cores.” Python does have multithreading, but threads run cooperatively, yielding to each other for CPU-bound work. And Python’s support for multiprocessing is ...
