It's time to revise Mastering Object-Oriented Python. While the previous edition is solidly focused on Python3, it lacks some important features:

• F-Strings
• Type Hints
• types.NamedTuple
• Data Classes

So. There's some stuff to add. I don't think there's too much to take away. I plan to make some things a …

Warning. I'm new to this. Yes, my book Functional Python Programming -- 2nd ed -- is full of type hints. But my examples are all (intentionally) relatively simple. There are edge cases that I do not pretend to understand.

Here's a fun one. Start here

Of these, most are important, but not specific to Python at all. Only items 3, 4, 7, and 8 are pretty specific to Python. They talk about the assert statement, some timing vulnerabilities …

Sadly.

There's a core conflict:

• The advantages of spreadsheets-as-database are numerous.
• The disadvantage is …

And yes, this is truncated because I left early, and missed some important things. I'm going to have to catch on YouTube https://www.youtube.com/channel/UCsX05-2sVSH7Nx3zuk3NYuQ/videos

Let's talk about the type hints, shall we?

Most of the examples have had type hints added. This means running everything through mypy. And it also means running everything through doctest, as well.

More important than the technical …

Read this. Goodbye, Object Oriented Programming I like this because parts of it are wrong, and parts are based on peculiarities of specific languages which aren’t problems in other languages.

The “wrong” things are on a spectrum. At one end are things almost right. The other end is hoped-for …
