小甲鱼python视频第九讲（课后习题）

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','']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','']
print(list1)
list1.insert(3,'forever')
print(list1)

3

list3 = ['小甲鱼',88,'黑夜',90,'迷途',85,'怡静',90,'秋舞斜阳',88]
for each in list3:
    print(each)

4(不会，看小甲鱼的)

list3 = ['小甲鱼',88,'黑夜',90,'迷途',85,'怡静',90,'秋舞斜阳',88]
count = 0
length = 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])
