How do I join dictionaries together in Python?
Python tip:
You can join two dictionaries using
**or|(for Python >= 3.9, works for all subclasses).If there are any duplicate keys, the second (rightmost) key-value pair is used.
user = {"name": "Jan", "surname": "Giacomelli"} address = {"address1": "Best street 42", "city": "Best city"} user_with_city = {**user, **address} print(user_with_city) # {'name': 'Jan', 'surname': 'Giacomelli', 'address1': 'Best street 42', 'city': 'Best city'} user_with_city = user | address print(user_with_city) # {'name': 'Jan', 'surname': 'Giacomelli', 'address1': 'Best street 42', 'city': 'Best city'} user_with_city = {"address": "Best street"} | {"address": "Almost best street"} print(user_with_city) # {'address': 'Almost best street'}
