python如何生成随机密码？

    import random

    def random_password():

        list1 = []

        #把字母加入序列中

        for i in range(65,90):

            list1.append(chr(i))

        for i in range(97,122):

            list1.append(chr(i))

        list2 = [1,2,3,4,5,6,7,8,9]

        list = list1 +list2

        n = 0

        while n < 10:

            password = []

            n = n + 1

            m = 0

            password = password + random.sample(list, 8)

            #把列表转化为字符串

            password_middle = [str(i) for i in password]

            password_end = ''.join(password_middle)

            print("第{}个随机生成的密码是：{}".format(n,password_end))

random_password()

#random.sample(seq, k)实现从序列或集合seq中随机选取k个独立的的元素

#random.randint(a, b)   #A-Z:65-90;a-z：97-122;ASCII码48～57为0到9十个阿拉伯数字
