I know for a function, it can return a list term.

def test():
    return [1, 2]


value1 = test()[0]
value2 = test()[1]
print(value1)  # 1
print(value2)  # 2

And I can also return them one by one.

def test():
    return 1, 2


value1, value2 = test()
print(value1)  # 1
print(value2)  # 2

And I really want to know, is there an operator <?> that can unzip list value [1, 2] to 1, 2? Such as:

def test():
    return <?>[1, 2]


value1 = test()[0]
value2 = test()[1]
print(value1)  # 1
print(value2)  # 2

The reason I ask this question is that, if I do not know exactly the number of elements in output list, and I still want to let them output one by one.

Before I tried * operator, but it failed, and the class also not support * in return function.

Maybe you will think this is not useful. But if we have two classes,

class Box:
    ...
class Taper:
    ...

And in another class, we want to return this class object which has several class objects. Then it becomes useful.

class shapes:
    def collect_all_shapes(self):
        obj = [Box(), Taper()]
        return obj
