Once we have tuples and lists, we may use a nice trick in assignment expression, based on the packing and unpacking of tuples.
>>> a, b, c = 1, 2, 3
Or, with lists,
>>> [a, b, c] = [1, 2, 3]
When you have a list (or a tuple) on the left-hand side of an assignment expression, you have to have a list of matching structure on the right-hand side. Then Python will "unpack" them both, and give to the individual components of the structure on the left side. You may get fancier with this function:
>>> thing = [8, 9, [1, 2], 'John', [33.3, 44.4]]
>>> [a, b, c, d, [e1, e2]] = thing
