They're not technically identical. If the thing returned is subscriptable (as with your list example), then I would definitely subscript it rather than unpacking; but if it's something iterable but not subscriptable, the unpack will still work. >>> def f(): yield 42 ... >>> result, = f() >>> result 42 >>> result = f()[0] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'generator' object is not subscriptable ChrisA -- https://mail.python.org/mailman/listinfo/python-list
