实验3

task1

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)

 

 

一 [1,100],能

二 [1,4],不包括5

(1,4),不包括

三 一定,s1是rang(5)

四 一定,len(s2)<5不满足停止运行

总结：通过本次实验，我知道了一定要随笔和pycharm同步完成，所有的代码写完并截图，然后发现代码没有复制保存真的太蠢了，照着自己的截图又重新敲了一遍，实在是太蠢了！
