def dict_compare(d1, d2):
    d1_keys = set(d1.keys())
    d2_keys = set(d2.keys())
    shared_keys = d1_keys.intersection(d2_keys)
    added = d1_keys - d2_keys
    removed = d2_keys - d1_keys
    modified = {o : (d1[o], d2[o]) for o in shared_keys if d1[o] != d2[o]}
    same = set(o for o in shared_keys if d1[o] == d2[o])
    return added, removed, modified, same

x = dict(a=1, b=2)
y = dict(a=2, b=2)
added, removed, modified, same = dict_compare(x, y)

我是python的新手，但我最终做了类似于@mouad的事情

unmatched_item = set(dict_1.items()) ^ set(dict_2.items())
len(unmatched_item) # should be 0

异或操作符(^)应该删除字典中的所有元素，如果它们在两个字典中都相同。

如果你想知道在两个字典中有多少值是匹配的，你应该这样说:)

也许是这样的:

shared_items = {k: x[k] for k in x if k in y and x[k] == y[k]}
print(len(shared_items))

在PyUnit中有一个比较字典的方法。我使用以下两个字典对它进行了测试，它完全符合您的要求。

d1 = {1: "value1",
      2: [{"subKey1":"subValue1",
           "subKey2":"subValue2"}]}
d2 = {1: "value1",
      2: [{"subKey2":"subValue2",
           "subKey1": "subValue1"}]
      }


def assertDictEqual(self, d1, d2, msg=None):
        self.assertIsInstance(d1, dict, 'First argument is not a dictionary')
        self.assertIsInstance(d2, dict, 'Second argument is not a dictionary')

        if d1 != d2:
            standardMsg = '%s != %s' % (safe_repr(d1, True), safe_repr(d2, True))
            diff = ('\n' + '\n'.join(difflib.ndiff(
                           pprint.pformat(d1).splitlines(),
                           pprint.pformat(d2).splitlines())))
            standardMsg = self._truncateMessage(standardMsg, diff)
            self.fail(self._formatMessage(msg, standardMsg))

我不建议在生产代码中导入unittest。我的想法是，PyUnit中的源代码可以重新配置，以在生产环境中运行。它使用pprint来“漂亮地打印”字典。调整这段代码以使其“适合生产”似乎很容易。

你可以用下面的方法写出你自己的函数。

class Solution:
    def find_if_dict_equal(self,dict1,dict2):
        dict1_keys=list(dict1.keys())
        dict2_keys=list(dict2.keys())
        if len(dict1_keys)!=len(dict2_keys):
            return False
        for i in dict1_keys:
            if i not in dict2 or dict2[i]!=dict1[i]:
                return False
        return True
        
    def findAnagrams(self, s, p):
        if len(s)<len(p):
            return []
        p_dict={}
        for i in p:
            if i not in p_dict:
                p_dict[i]=0
            p_dict[i]+=1
        s_dict={}
        final_list=[]
        for i in s[:len(p)]:
            if i not in s_dict:
                s_dict[i]=0
            s_dict[i]+=1
        if self.find_if_dict_equal(s_dict,p_dict):
            final_list.append(0)
        for i in range(len(p),len(s)):
            element_to_add=s[i]
            element_to_remove=s[i-len(p)]
            if element_to_add not in s_dict:
                s_dict[element_to_add]=0
            s_dict[element_to_add]+=1
            s_dict[element_to_remove]-=1
            if s_dict[element_to_remove]==0:
                del s_dict[element_to_remove]
            if self.find_if_dict_equal(s_dict,p_dict):
                final_list.append(i-len(p)+1)
        return final_list

下面的代码将帮助您比较python中的dict列表
