python如何生成随机密码？

import random

random.seed(0x1010)  #设置随机种子数

    #设置种子选择空间

s = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!@#$%^&*"

ls = [] #存取密码的列表

FirstPsw = "" #存取第一个密码的字符

while len(ls)<20:  #十个随机密码

    pwd = ""

    for i in range(10):

        pwd += s[random.randint(0,len(s)-1)]

    if pwd[0] in FirstPsw:

        continue

    else:

        ls.append(pwd)

        FirstPsw +=pwd[0]

fo = open("随机密码.txt","w",encoding ="utf-8")

fo.write("\n".join(ls))

fo.close()

#-*-coding:utf_8-*-

import random,string    #调用random、string模块

src_digits = string.digits              #string_数字

src_uppercase = string.ascii_uppercase  #string_大写字母

src_lowercase = string.ascii_lowercase  #string_小写字母

count = int(input("请输入生成密码个数："))

for i in range(count):

    #随机生成数字、大写字母、小写字母的组成个数（可根据实际需要进行更改）

    digits_num = random.randint(1,6)

    uppercase_num = random.randint(1,8-digits_num-1)

    lowercase_num = 8 - (digits_num + uppercase_num)

    #生成字符串

    password = random.sample(src_digits,digits_num) + random.sample(src_uppercase,uppercase_num) + random.sample(src_lowercase,lowercase_num)

    #打乱字符串

    random.shuffle(password)

    #列表转字符串

    new_password = ''.join(password)

    print(new_password)
