Did you try ?-) Took me about 30'':
>>> def fun(): return 1,2,3
...
>>> a = fun()
>>> a
(1, 2, 3)
>>> def fun2(): return 1,2,3,4,8,9
...
>>> b = fun2()
>>> b
(1, 2, 3, 4, 8, 9)
>>>
It of course works since a function *always* returns a *single* value.
Now this value *can* be a sequence, and this sequence *can* be unpacked
- directly at the return of the function, or latter:
>>> a = fun()
>>> a
(1, 2, 3)
>>> v1, v2, v3 = a
>>> v1
1
>>> v2
2
>>> v3
3
>>>
