This is a short example of a new "typed" named tuple syntax (Python 3.6). It's a very clean and easy way to define data classes with a type hinting and inheritance support.
from typing import NamedTuple # >= Python.3.6.0
class Employee(NamedTuple):
name: str
department: str
salary: int
is_remote: bool = False # >= Python.3.6.1
bob = Employee(name='Bob', department='IT', salary=10000, is_remote=True)

Mypy shows the error of an unsupported comparison operator but this class has `@functools.total_ordering`, `==` and `<`, so `<=` is implemented for this type.
import decimal
import functools
import typing
@functools.total_ordering
class Money:
def __init__(self, amount: str) -> None:
self.amount = decimal.Decimal(amount)
