Getting ready to move neighborhoods next month. The current place is just walking distance from a beautiful trail. So I'm savoring it while we're still here!

My first swing at chord melody! Love this tune even more on guitar.

Squeaked in one Inktober drawing this year! Very much directly inspired by the energetic ink work of Violaine Briat's Lil' Dee.

So much of JavaScript/TypeScript is massaging data returned from an endpoint through JSON. TypeScript has the lovely ability to type the objects and their properties that come through.

While Python is not as strongly typed as TypeScript, we have this benefit built in to the type hinting system.

It's easier shown than explained:

from typing import Union, TypedDict
from datetime import datetime


class Concert(TypedDict):
    """
    Type Dict for concert dictionaries.
    """

    id: str
    price: int
    artist: str
    show_time: Union[str, datetime]

All pretty straightforward. We're instantiating a class, inheriting from the TypedDict base class. Then we set our expected properties as values on that class.

It's ideal to store a class like this in it's own types directory in your project.

A couple of nice ways to use this:

First, you can use this in your methods where you are expecting to receive this dictionary as an argument:

def get_concert_ticket_details(
        self, concert: UnitDict = None
    ) -> tuple(list[str], set[str]):
    // Do work

You can also directly create a dictionary from this class through instantiation.

concert = Concert({
    "id": "28",
    "price": 50,
    "artist": "Prince",
    "show_time": show_time
})

The benefit of both is, of course, the suggestion in your editor letting you know that a property does not match the expected shape.

Today I learned that this jazz standard is named after margarine. Yum!
