亲，您好！你可以使用Python的random模块来生成随机整数，并使用列表来存储不同范围的整数。以下是实现这个功能的代码：importrandomlist1=[]for_inrange(10):num=random.randint(0,100)ifnum=60:list2.append(num)list1.sort(reverse=True)list2.sort(reverse=True)count1=len(list1)count2=len(li...
python实现0~100的平方和,用sum()函数接收一个list作为参数, 并返回list所有元素之和。请计算 1*1 + 2*2 + 3*3 + ... + 100*100。 2.来吧展示: 1 2 3 4 5 6 7 L=[] x=1 whilex <=100: L.append(x*x) x=x+1 print(sum(L)) ...

Python使用range可以创建数值列表。下面可以正确输出600以内6的倍数的语句是?(D) A. print(list(range(100, 600, 6))) B. print(list(range(0, 600, 10))) C. print(list(range(1, 601, 6))) D. print(list(range(6, 601, 6)))
