Get non-matching data when comparing python dicts and store them -

i have 2 python dicts... i'm checking if match. how can non-matched keys , values items , store them?

data1 = {'first_name': 'john', 'last_name': 'doe', 'username': 'johndoe'}  data2 = {'first_name': 'john', 'last_name': 'doe', 'username': 'johohoho'}  (key, value) in set(data1.items()) & set(data2.items()):         print(key, value)  # returns matching data. how can grab non matched? 

thank in advance!

you can use xor non matching entries catching matched entries:

>>> (key, value) in set(data1.items()) ^ set(data2.items()): ...         print(key, value)  ...  ('username', 'johndoe') ('username', 'johohoho') 

note: won't work nested dictionaries
