如果順序無關緊要，請使用set.intersection：A = [(1.1,2.2),(3.3,4.4),(5.5,6.6)]

B = [(1.1,2.2),(7.7,8.8),(3.3,4.4)]

print(set(A).intersection(B))

set([(3.3, 4.4), (1.1, 2.2)])

或者將B設為集合，并在a上迭代保持公共元素：

^{pr2}$

如果要查找具有相同屬性值的對象：A = [Point(1.1,2.2),Point(3.3,4.4),Point(5.5,6.6)]

B = [Point(1.1,2.2),Point(7.7,8.8),Point(3.3,4.4)]

st = set((p.a,p.b) for p in B)

print([p for p in A if (p.a,p.b) in st])

或者在類中創建哈希方法：class Point(object):

def __init__(self, a_, b_):

self.a = a_

self.b = b_

def __hash__(self):

return hash((self.a, self.b))

def __eq__(self, other):

return self.a, self.b == other.a,other.b

def __ne__(self, other):

return not self.__eq__(other)

A = [Point(1.1,2.2),Point(3.3,4.4),Point(5.5,6.6)]

B = [Point(1.1,2.2),Point(7.7,8.8),Point(3.3,4.4)]

print(set(A).intersection(B))
