An empty class definition -will do nicely:: +"struct", bundling together a few named data items. The idiomatic approach +is to use :mod:`dataclasses` for this purpose:: - class Employee: - pass + from dataclasses import dataclasses - john = Employee() # Create an empty employee record + @dataclass + class Employee: + name: str + dept: str + salary: int - # Fill the fields of the record - john.name = 'John Doe' - john.dept = 'computer lab' - john.salary = 1000 +:: + + >>> john = Employee('john', 'computer lab', 1000) + >>> john.dept + 'computer lab' + >>> john.salary + 1000 A piece of Python code that expects a particular abstract data type can often be passed a class that emulates the methods of that data type instead.
