Nice course. Looks like good, practical material for people who want to dive in.
Side note, this example made me pause and be grateful that I'm no longer professionally writing in python as much as I used to be:
@shares.setter
def shares(self, value):
if not isinstance(value, int):
raise TypeError('Expected int')
self._shares = value
I still use python if I'm doing prototyping, exploring APIs or ideas, etc. But I try not to roll it into production unless it's an inconsequential program.
I’m in the midst of a python project right now - I’m fairly familiar with python but I haven’t used in a while, preferring TS. I’m currently majorly kicking myself for not starting out with mypy. Unfortunately even with mypy, soundness guarantees are nowhere near as powerful as TS, and the typing ecosystem is lacking (no definitely-typed equivalent i know of), so working with libraries is pretty much just guesswork. I really have no clue why people love this language so much.
> why people love this language so much
Because no matter what problem you have, after 12 minutes of googling, you can pip install foo. The language almost doesn't matter because most programming is via library api.
I can do the same with npm, but if there’s a @types available (or better yet built in), I barely have to read long-form documentation and I get smart completions with documentation, types, etc right in my editor, specific to the exact expression I’m editing.
And...exactly the same with mypy, either via in-library typings or the typeshed.
Projects in the npm ecosystem may be somewhat more likely to.have typings if the project exists, but I find that, for anything other than web frontend, where JS is obviously king, the tool I'm looking for is more likely to actually exist in the python ecosystem.
Are there mypy typings available for things like sci-py and simpletransformers, and if so how do I acquire them?
Automatic stub generation may also be helpful [3]
