实验3
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)
问题1： random.randint(1,100) 生成的随机整数范围是？能否取到100？
1-99 不能
问题2：利用 list(range(5)) 生成的有序序列范围是？是否包括5？利用 list(range(1,5)) 生成的有序序列范围是？是否包括5？
0-4 不包括5 1-4 不包括5
问题3：使用line8生成的集合s1，len(s1)一定是5吗？
不一定是
问题4：使用line12-14生成的集合s2，len(s2)一定是5吗？
一定是
