如果我用平面眼检查看起来有相同的值，但如果我把它们放在同一个函数中，结果会有所不同。如何确定这两者具有完全相同的类型和相同的值？
答案 0 :(得分：2)
两个lists 不相同。这就是为什么function可能会为不同的lists提供不同的结果。
要检查，如果 2 lists 相同，您可以执行以下操作：
list1 == list2
所以举一些例子：
>>> [1, 2, 3, 4, 5] == [1, 2, 3, 4, 5]
True
>>> [1, 2, 3, 4, 5] == [1, 2, 3, 4, 3]
False
>>> [1, 2, 3, 4, 5] == [5, 4, 3, 2, 1]
False
>>> [(1, 2), (3, 4)] == [(1, 2), (3, 4)]
True
>>> [(1, 2), (3, 4)] == [(1, 2), (3, 5)]
False
如果您想查找differences的内容，可以执行以下操作：
[e for e in list1 if e not in list2] + [e for e in list2 if e not in list1]
我认为实际上非常可读。
所以我们可以把它放在function：
def comp(list1, list2):
return [e for e in list1 if e not in list2] + [e for e in list2 if e not in list1]
和一些例子：
>>> comp([1, 2, 3], [1, 2, 3]) #should be empty as no differnence
[]
>>> comp([(1, 2), (3, 4)], [(1, 2), (3, 5)])
[(3, 4), (3, 5)]
>>> comp([(1, 2), (3, 4)], [(1, 2), (3, 5), (6, 7)])
[(3, 4), (3, 5), (6, 7)]
