Dict override __eq__, dùng == so sánh bằng giá trị.
Ví dụ ==
a = {'foo': 10, 'bar': 150}
b = {'foo': 10, 'bar': 150}
print(a == b) # True
Tìm shared items: dùng set(a.items()) & set(b.items()).
a = {'foo': 10, 'bar': 150}
b = {'foo': 10, 'baz': 50}
shared = set(a.items()) & set(b.items())
print(shared) # {('foo', 10)}
