Python Tuple - GeeksforGeeks geeksforgeeks.org Python Tuple is a collection of Python objects separated by commas. Tuples are immutable, and usually, they contain an heterogeneous sequence of elements that are accessed via unpacking or indexing (or even by attribute in the case of namedtuples)....
Everything in Python is an object, or so the saying goes. If you want to create your own custom objects, with their own properties and methods, you use Python’sclassobject to make that happen. But creating classes in Python sometimes means writing loads of repetitive, boilerplate code to ...
Another possible work-around is to use the collections.namedtuple class: from collections import namedtuple def create_user(input): User = namedtuple('User', input.keys()) return User(**input) user = json.loads(json_obj, object_hook=create_user) print(f"User {user.name.first} {user.name...
