实验3 控制语句与组合数据类型应用编程

task1.py

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.random.randint(1,100)生成的整数范围可以取到100.

2.list(range(5))和list(range(1,5))生成的有序数列范围都不包含5.

3.len(s1)一定是5.

4len(s2)一定是5.
