计算机随机生成两个0-9的数字,由用户判断其和的值,直到用户答对为止。程序如图所示,横线处的代码是以下哪个选项?
A: (num1+num2)isnot answer:
B: (num1+num2)==answe:
C: (num1+num2)!=answer:
D: (num1+num2)=answer:
A: (num1+num2)isnot answer:
B: (num1+num2)==answe:
C: (num1+num2)!=answer:
D: (num1+num2)=answer:
举一反三
- 中国大学MOOC: 执行如下代码片段后，num的值为：int num = 5;num = (num % 2) == 0 ? num – 1 : num + 1;
- 编写一个函数判断客户输入一个数字为1位、2位还是更多为，代码如下：请补全空下的代码num=int(input("输入一位或两位的数字:"))n='0'(1)n='1'(2)n='2'(3)d='>;2'print(n+"位数。”) A: 1: if num>;-10 and num<;10:2: eilf num >;-100 and num<;100:3: else: B: 1: if num>;10 and num<;-10:2: eilf num >;-100 and num<;100:3: else: C: 1: if num>;-10 and num<;10:2: eilf num <;-100 and num>;100:3: elif: D: 1: if num>;-100 and num<;100:2: eilf num >;-10 and num<;10:3: else:
- 执行如下代码片段后，num的值为：int num = 5;num = (num % 2) == 0 ? num – 1 : num + 1; A: 1 B: 4 C: 5 D: 6
- 回文数判断。如果n的各位数字反向排列所得自然数与n相等,则n被称为回文数。从键盘输入一个5位数字,判断是否是回文数的条件是( ) A: num[0]==num[-1] B: num[0]==num[-1] and num[1]==num[-2] C: num[1]==num[-2] D: num[0:L-1]==num[-1:-L]
- 下列程序的输出结果是（） num = 27 count = 0 while num > 0: if num % 2 == 0: num /=2 elif num % 3 ==0: num /= 3 else: num -=1 count += 1 print (count)
