tuple是含有10个元素的元组，下列说法不正确的是： A: 访问tuple元组可以这样：tuple[1] B: 访问tuple元组可以这样：tuple[:5] C: tuple[3] = “python” D: tuple = tuple[:5] + ("python",) + tuple[5:]

tuple = (1, 2, 3, 4, 5) print(tuple[3]) tuple元组输出的结果为3。

Python中,对于定义的元组tuple = (1, 2, 3),以下各项操作能成功执行是()。 A: tuple[2]=4 B: tuple[0]=() C: tuple[0]=None D: tuple = (4, 5, 6)

使用while 语句实现打印出1至10.count = 1while ( ) print (count) count = count + 1 A: count B: True C: count D: count

有两个列表:list1=[(2),{0},(1),(8)]，list2=[(2,),(0,),(1,),(8,)]，那么type(list1[0])和type(list2[0])分别是( ) A: int和tuple B: int和int C: tuple和tuple D: tuple和int

count = 0 while count < 5: print (count, " 小于 5") count = count + 1 else: print (count, " 大于或等于 5")

阅读以下程序public class Count{static int count;int number;public Count(){count = count + 1;number = count;}}class Test{public static void Main(){Count a = new Count();Count b = new Count();Count c = new Count();}}程序运行后，对象a的count值是（） A: 0 B: 1 C: 2 D: 3

下面的代码段执行之后count的值是什么( ) int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count); int count = 1; for(int i = 1; i <= 5; i++) { count+= i; } System.out.println(count);

下面的代码段执行之后count的值是什么( ) int count = 1; for (int i = 1; i <= 5; i++) { count += i; } System.out.println(count);

The output of the following code is ____.<br/>count = 1; /* initialize count */ while (count &lt;= 10) { printf("%d ",count); count++; /* increment count */ } A: 1 1 1 1 1 1 1 1 … B: 1 2 3 4 5 6 7 8 9 C: 1 2 3 4 5 6 7 8 9 10 D: 1 2 3 4 5 6 7 8 9 10 11
