有没有pythonic方法解压缩第一个元素中的列表和单个命令中的"尾部"？

例如:

>> head, tail = **some_magic applied to** [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
>> head
1
>>> tail
[1, 2, 3, 5, 8, 13, 21, 34, 55]

如何在一行中列出多个赋值.

>>>a,b,c = [1,2,3]
>>> a
1
>>>b
2
>>>c
3

但是我应该怎么做才能分配其余的子数组 c

>>> a,b,c = [1,2,3,4,5,6,7,8,9] ##this gives an error but how to ..?
>>> a
1
>>>b
2
>>>c
[3,4,5,6,7,8,9]

这该怎么做？

在红宝石中我可以做类似的事情:

key, *rest = ["key1", 1, 2, 3]

结果将是:

key = "key1"
rest = [1, 2, 3]

有没有办法在python中做同样的事情？

我正在尝试从中提取前三个项目numbers,并将它们分配给三个不同的变量,如下所示:

numbers = [1,2,3,4,5,7,8,9,10]
[first_item, second_item, third_item] = numbers

为什么我收到此错误？

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    [first_item, second_item, third_item] = numbers
ValueError: too many values to unpack
