实验三 控制语句与组合数据类型综合应用编程

# task1.py
import random

print('用列表存储随机整数： ')
Is = [random.randint(1,100)for i in range(5)]
print(Is)

print('\n用集合存储随机整数：')
s1 = {random.randint(1,100) for i in range(5)}
print(s1)

print('\n用集合存储随机整数： ')
s2 = set()
while(len(s2)<5):
    s2.add(random.randint(1,100))
print(s2)

问题1：范围是1~100，可以取到100

问题2：不包括5；

　　　　包括5.

问题3：不一定是5

问题4：一定是5
