代码示例1（8位）

import random
import string


total = string.ascii_letters + string.digits + string.punctuation


length = 8


password = "".join(random.sample(total, length))

print(password)

代码示例2（任意）

import random
import math


alpha = "abcdefghijklmnopqrstuvwxyz"
num = "0123456789"
special = "@#$%&*"


# 输入密码长度
pass_len = int(inwww.devze.comput("输入密码长度"))


# 设置密码长度组成格式，字母数字和特殊符号占比，以下示例50-30-20比例分配
alpha_len = pass_len//2
num_len = math.ceil(pass_len*30/100)
special_len = pass编程_len-(alpha_len+num_len)


password = []


def generate_pass(length, array, is_alpha=False):
       for i in range(length):
        index = random.randint(0, len(array) - 1)
        character = array[index]
        if is_alpha:
            case = random.randint(0, 1)
            if case == 1:
                character = character.upper()
        password.append(character)


# 字符
generate_pass(alpha_len, alpha, 编程客栈True)
# 数字
generate_pass(num_len, num)
# 特殊符号
generate_pass(special_len, special)
# 打乱顺序
random.shuffle(password)
# 转列表到字符串
gen_password = ""
for i in password:
    gen_password = gen_password + str(i)
print(gen_password)

除了上面的两个示例代码，小编还为大家整理了一些python实现生成随机密码的方法，希望对大家有所帮助

python实现生成随机 字母 + 数字密码

#coding:utf-8
import random,string编程客栈
def GetPassword(length):
  # 随机生成数字个数
  Ofnum=random.randint(1,length)
  Ofletter=length-Ofnum
  # 选中ofnum个数字
  slcNum=[random.choice(string.digits) for i in ra编程nge(Ofnum)]
  # 选中ofletter个字母
  slcLetter=[random.choice(string.ascii_letters) for i in range(Ofletter)]
  # 打乱组合
  slcChar=slcLetter+slcNum
  random.shuffle(slcChar)
  # 生成随机密码
  getPwd=''.join([i for i in slcChar])
  return getPwd
if __name__=='__main__':
  print( GetPassword(6)) #GetPassword()自定义随机密码长度

Python随机生成带特殊字符的密码

#!/usr/bin/env python
import string
from itertools import chain
from random import choice, sample
def mkpasswd(length=12, digits=4, upper=3, lower=3):
lowercase = string.lowercase
uppercase = string.uppercase
salt = '!@#$%^&*()><?'
password = list(
chain(
(choice(uppercase) for _ in range(upper)),
(choice(lowerca开发者_Go开发se) for _ in range(lower)),
(choice(string.digits) for _ in range(digits)),
(choice(salt) for _ in range((length - digits - upper - lower)))
)
)
return "".join(sample(password, len(password)))
if __name__ == '__main__':
print mkpasswd()
#!/usr/bin/env python
import string

def mkpasswd(length=12, digits=4, upper=3, lower=3):
lowercase = string.lowercase
uppercase = string.uppercase
salt = '!@#$%^&*()><?'
password = list(
chain(
(choice(uppercase) for _ in range(upper)),

(choice(salt) for _ in range((length - digits - upper - lower)))
)
)
return "".join(sample(password, len(password)))
if __name__ == '__main__':
print mkpasswd()
