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)

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])
