Python生成随机字符串

利用Python生成随机域名等随机字符串。

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from random import randrange, choice
from string import ascii_lowercase as lc
from sys import maxsize
from time import ctime

tlds = ('com', 'edu', 'net', 'org', 'gov')

for i in range(randrange(5, 110)):
    dtint = randrange(maxsize/1000)  # pick date
    dtstr = ctime(dtint)        # date string
    llen = randrange(4, 8)      # login is shorter
    login = ''.join(choice(lc) for j in range(llen))
    dlen = randrange(llen, 13)
    dom = ''.join(choice(lc) for j in range(dlen))
    print('%s::%s@%s.%s::%d-%d-%d' % (dtstr, login, dom, choice(tlds), dtint, llen, dlen))

该脚本生成拥有三个字段的字符串，由一对冒号或者一对双冒号分隔。第一个字段是随机整数，该整数将被转换为一个日期。下一个字段是一个随机生成的电子邮件地址。最后一个字段是一个由单横线（-）分隔的整数集。

输出结果如下
