        else:
            print("z is middle y is the smallest")
    else:
        print("z is the biggest")

e.串列 list
串列可以有整數，浮點數，字串，tuple元組，list串列切片
list串列[]
tuple元組()
dict字典{：}
集合{,}
list_name[:]切片全部
list_name[:n]從1到n
list_name[n:]從n到最後
list_name[n:n]從n到n
list_name[開始：結束：：間隔值]
index 0~5（正向） or -1~-6（逆向）
