如果顺序无关紧要，则可以使用相同的方法，但是将第一和第二个元素的元组用作键:

If the order doesn't matter, you can use that same method but using a tuple of the first and second elements as the key:

dict(((x[0], x[1]), x) for x in L).values()

或者在Python 2.7和更高版本上:

Or on Python 2.7 and higher:

{(x[0], x[1]): x for x in L}.values()

您可以使用tuple(x[:2])代替(x[0], x[1])，只要您认为可读性更高即可.

Instead of (x[0], x[1]) you can use tuple(x[:2]), use whichever you find more readable.
