请问这道怎么做啊????要和输出示例格式一样????

import random

#定义统计字符函数
def char_num(n):
    count = 0
    for i in a:
        if i in n:
            count += 1
    if count >3:
        print("该集合重复元素超过3个")
    else:
        print("该集合重复元素未超过3个")

#随机生成3个集合
x = set()
y = set()
z = set()
a = {1, 2, 3, 4, 5}
for i in range(10):
    a1 = random.randint(0, 9)
    a2 = random.randint(0, 9)
    a3 = random.randint(0, 9)
    x.add(a1)
    y.add(a2)
    z.add(a3)
print("第1个集合：", x)
char_num(x)
print("第2个集合：", y)
char_num(y)
print("第3个集合：", z)
char_num(y)
