Python随机生成8位密码的示例详解

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(input("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_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, 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)

知识补充

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