Python 列表多重赋值

Question

How to do Python list multiple assignment in one line.

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

but what should I do to assign rest of the sub array to 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]

how to do this?

Answer 1

You can use Extended iterable unpacking : by adding * in front of c , c will catch all (rest) items.

>>> a, b, *c = [1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> a
1
>>> b
2
>>> c
[3, 4, 5, 6, 7, 8, 9]

Answer 2

first Assign the list to a like this:

a= [1,2,3,4,5,6,7,8,9]

assign second element to 'b' with:

b=a[1]

assign rest of the elements to 'c' with:

c=a[2:9]

then reassign first element to 'a':

a=a[0]

here we go. :)
