python--随机生成8为大小写字母数字组成的密码

import random,string    #调用random、string模块


def create_password():

    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
    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)
    return new_password
