小甲鱼python视频第九讲(课后笔)

1.列表里可以存放什么东西?

可以存放任何的数据类型,

list1 = [我爱你,i love you,1314]print(list1)

2.向列表中添加元素

append(将参数作为一个元素添加到列表的结尾)

list1 = [我爱你,i love you,1314]print(list1)list1.append([forever‘,‘just you‘])print(list1)

extend  (将参数作为一个列表添加到列表的结尾)         

list1 = [我爱你,i love you,1314]print(list1)list1.extend([‘forever‘,‘just you‘])print(list1)

insert(将参数插入到列表)

list1 = [我爱你,i love you,1314]print(list1)list1.insert(3,forever)print(list1)

list3 = [小甲鱼,88,黑夜,90,迷途,85,怡静,90,秋舞斜阳,88]count = 0length = len(list3)while count < length:    print(list3[count],list3[count+1])    count += 2
list3 = [小甲鱼,88,黑夜,90,迷途,85,怡静,90,秋舞斜阳,88]for each in range(len(list3)):    if each%2 == 0:        print(list3[each],list3[each+1])
