本文介绍Python3中String模块ascii_letters和digits方法，其中ascii_letters是生成所有字母，从a-z和A-Z,digits是生成所有数字0-9.string.punctuation是所有标点‘!"#$%&\‘()*+,-./:;<=>[email protected][\\]^_`{|}~‘
String模块中的常量：
string.digits：数字0~9
string.ascii_letters：所有字母（大小写）
string.lowercase：所有小写字母
string.printable：可打印字符的字符串
string.punctuation：所有标点
string.uppercase：所有大写字母
>>> import string
>>> string.digits
‘0123456789‘
>>> string.letters
‘ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz‘
>>> string.lowercase
‘abcdefghijklmnopqrstuvwxyz‘
>>> string.printable
‘0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!"#$%&\‘()*+,-./:;<=>[email protected][\\]^_`{|}~ \t\n\r\x0b\x0c‘
>>> string.punctuation
‘!"#$%&\‘()*+,-./:;<=>[email protected][\\]^_`{|}~‘
>>> string.uppercase
‘ABCDEFGHIJKLMNOPQRSTUVWXYZ‘
import random, string
def rand_str(num, length=7):
f = open(‘pwd_code.txt‘, ‘w‘)
for i in range(num):
chars = string.ascii_letters + string.digits+string.punctuation
s = [random.choice(chars) for i in range(length)]
f.write(‘{0}\n‘.format(‘‘.join(s)))
f.close()
if __name__ == ‘__main__‘:
rand_str(200)
python2 方法一、
#!/usr/bin/env python # -*- coding: utf-8 -*- import random import string #第一种方法 seed = "[email protected]#$%^&*()_+=-" sa = [] for i in range(8): sa.append(random.choice(seed)) salt = ‘‘.join(sa) print salt
方法二、
#!/usr/bin/env python # -*- coding: utf-8 -*- import random import string salt = ‘‘.join(random.sample(string.ascii_letters + string.digits, 8)) print salt
