下面程序的运行结果为。 def swap(list): temp=list[0] list[0]=list[1] list[1]=temp list=[1,2] swap(list) print(list)

获取列表list=[1，2，3，4]第一个元素正确的方法是（）。 A:  list[-1] B:  list[1] C:  list[0] D:  list[[1]]

代码如下 #函数定义 def chanageList(list): list.append(" end") print("list",list) #调用 strs =['1','2'] chanageList() print("strs",strs) 下面对 strs 和 list 的值输出正确的是 A: strs ['1','2'] list ['1','2'] B: strs ['1','2','end'] list ['1','2','end'] C: list ['1','2','end'] strs ['1','2','end'] D: list ['1','2','end'] strs ['1','2']

列表list = [1,2,3,4,5],下列选项中不能访问list末尾元素语句的是( )。 A: list[4] B: list[-1] C: list[len(list)-1] D: list.tail()

已知定义一个列表 list = [1,2,3,4,5]，下面哪种操作会导致越界？ A: list[0] B: list[5] C: list[-1] D: list[1]

检查list第2个元素是否可用，以下哪个写法正确？ A: if (list != null) {.....} B: if (list.size()>1) {.....} C: if (list != null && list.size()>1) {.....} D: if (list != null && list.get(1) != null ) {.....}
