    x += a is not always the same as x = x + a >>> x = y = [1] >>> x += [2] >>> x, y # return ([1, 2], [1, 2]) >>> x = x + [3] >>> x,y # return ([1, 2, 3], [1, 2]) That is because `+=` calls __iadd__ method while `+` calls __add__. Another example 👇

    Dear Python: >>> a = [1, 2, 3] >>> a += (3, 4, 5) >>> a [1, 2, 3, 3, 4, 5] >>> a = [1, 2, 3] + (3, 4, 5) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: can only concatenate list (not "tuple") to list ?
