python实现随机密码字典生成器示例

本来想穷举所有密码,算法要么就嵌套太深,要么就特别耗内存(会溢出).后来选了一个简单重复概率很低的算法.代码如下:

# -*- coding:utf-8 -*-
'''
 @ function: 生成随机密码字典
'''
import random
class dictor():
    cset=' abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789~!@#$%^&*()_-+=/*<>:;\'"[]{}|'
    def __init__(self,minlen,maxlen):
        if maxlen>minlen:
            self.__minlen=minlen
            self.__maxlen=maxlen
        else:
            self.__minlen=maxlen
            self.__maxlen=minlen
    def __iter__(self):
        return self
    def __next__(self):
        ret=''
        for i in range(0,random.randrange(self.__minlen,self.__maxlen+1)):
            ret+=random.choice(dictor.cset)
        return ret
if __name__=='__main__':
    for str in dictor(6,16):
        print(str)
