The tweet has since been deleted. Here's the old text

At this point, we're closing in on 9/13 (70%) of the way through the 2nd edition rewrite.

Important changes.

1. Type Hints
2. Type Hints
3. Type Hints

First.

Every single class, method, or function has to be changed to add hints. Every. Single. One. This is kind of huge. The book …

This seemed like an interesting problem. I hope this isn't someone's take-home homework or an interview question. It seemed organic enough when I found out about it.

Given a document like this...

doc = {
    "key": "the key",
    "tag1": ["list", "of", "values"],
    "tag2": ["another", "list", "here"],
    "tag3": ["lorem", "ipsum", "dolor"],
}

We want …

Using the clear() method of a dict isn't *wrong*. But. The reasons have to be investigated. I got a question about this code not working "properly." ("Properly"? Seems too vague to be useful.)

Here's a summary of the example.

final_list = []
temp_dict = {}
for obj in some_source:
    cool_function(obj, temp_dict)
    final_list.append …

This drifted into some serious rethinking of bad design decisions. (If someone else did this, I'd call it weak, and suggest improvements. It was me. It was bad. I'm a bad programmer and I feel bad about it.)

An an example, there's this …

some_data = {name: source[name] for name in the_names}
the_object = SomeClass(**some_data)

I think there's space for a Building Skills in Functional Python title next to the Building Skills in OO Design.
