比较包含字典列表值的字典

Question

我有两个字典：

    dict1 = {'Warning': [{'User account': 'User doesnot exist'},
                         {'Login': 'Login failed'}],
             'Error': [{'Monitoring': 'Monitoring failed due to system crash'},
                       {'Scheduler': 'Scheduler stopped running'}]}

dict2 = {'Warning': [{'User account': 'User doesnot exist'},
                     {'Login': 'Multiple logins attempted'},
                     {'Version': 'Version doesnot match'}],
         'Error': [{'Monitoring': 'Monitoring failed due to system crash'},
                   {'Scheduler': 'Scheduler never inititated'}],
         'Critical': [{'Memory': 'Memory overflow'}]}

我必须比较两个字典，如果dict2的值（字典列表）在dict1中不常见，则必须返回它们： 预期的输出是：

result = {'Warning': [{'Login': 'Multiple logins attempted'},
                      {'Version': 'Version doesnot match'}],
          'Error': [{'Scheduler': 'Scheduler never inititated'}],
          'Critical': [{'Memory': 'Memory overflow'}]}

我们非常感谢您的帮助。
