实验3 控制语句与组合数据类型综合应用编程

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

1.生成的范围是1-100，包括1和100

2.[0,1,2,3,4]不包括5

[1,2,3,4],不包括5

3.是的

4.是的
