下面哪一个是错误的?

A.使用len(列表名)测量元素的个数names_list=["zhangsan","lisi","wangwu"]print(len(names_list))

B.使用列表名[下标]获取列表的某个元素，例如：names_list=["zhangsan","lisi","wangwu"]print(names_list[2])

C.向列表中添加新元素有三个方法：append、extend、insert，例如：names_list=["zhangsan","lisi","wangwu"]names_list.append("zhaoliu")names_list.extend(["zhaoliu","liqi"])names_list.insert(1,"zhaoliu")print(names_list)

D.已有列表nums=[11,22,33,44,55],使用while循环遍历列表nums=[11,22,33,44,55]i=0 whilei

print(nums[i])i+=1
