Unpacking into a list
python
Solution
Absolutely nothing, even down to the bytecode (using `dis`):
>>> def list_assign(args):
[x, y, z] = args
return x, y, z
>>> def tuple_assign(args):
x, y, z = args
return x, y, z
>>> import dis
>>> dis.dis(list_assign)
2 0 LOAD_FAST 0 (args)
3 UNPACK_SEQUENCE 3
6 STORE_FAST 1 (x)
9 STORE_FAST 2 (y)
12 STORE_FAST 3 (z)
3 15 LOAD_FAST 1 (x)
18 LOAD_FAST 2 (y)
21 LOAD_FAST 3 (z)
24 BUILD_TUPLE 3
27 RETURN_VALUE
>>> dis.dis(tuple_assign)
2 0 LOAD_FAST 0 (args)
3 UNPACK_SEQUENCE 3
6 STORE_FAST 1 (x)
9 STORE_FAST 2 (y)
12 STORE_FAST 3 (z)
3 15 LOAD_FAST 1 (x)
18 LOAD_FAST 2 (y)
21 LOAD_FAST 3 (z)
24 BUILD_TUPLE 3
27 RETURN_VALUE
Problem
Is there any difference in Python between unpacking into a tuple: ``` x, y, z = v ``` and unpacking into a list? ``` [x, y, z] = v ```
