> nothing about type annotations constrains Python code at all Sorry, but this is just not true. Don't get me wrong, I write typed Python 99% of the time (pyright in strict mode, to be precise), but you can't type check every p

If I understand correctly, defining the protocol like this forces the implementation classes to have the members as proper fields and disallows properties. If you define `diameter` as a property in the protocol, it supports both: from

How big is your screen? At 27", I can clearly see pixels on 1440p. A 4k display with 150% scaling (effectively 1440p) looks much better. Maybe you haven't used a higher resolution? If so, you might not know what you're missin

How many such extreme situations do you encounter in your daily life? Most people will not face situations like these, so "never lie" is reasonable.

Parent's example had a direct `iter(thing)`. Even if you had to use `iter(thing, sentinel)`, you'd still use `for val in iter(thing, sentinel)`, not while.

This is about Python decorators: https://docs.python.org/3/glossary.html#term-decorator . In summary, they are functions that return functions, which allow you to wrap their behaviour (e.g. add a cache, transform a func

Yes, please. Given I'm forced to use Python, I'd welcome any "compile time" tools I can get. These days, it's using pyright with strict mode, which is pretty good, but there's still a long way to go.

You can use `if (response := get_user_input()) is not None` if that's important. IME, empty strings and None would be treated the same way.

Isn't this equivalent to just `for val in thing`?

by maleldil 2y ago
I disagree. First of all, it takes a minute to search "python :=", and the construct itself is pretty simple. It's been part of the language since 2018[0]. I don't think "not knowing the language" is a good rea

Linters complain because f"hello" and "hello" are the _exact_ same string. t"hello" isn't even a string.

That's the whole point. If you build something on top of open source code, your code should be open source too.

This would be fine in an ideal world. However, the one we live in has crawlers that don't care how many resources they use. They're fine with taking the server down or bankrupting the owner as long as they get the data they want.

It's true that simonw writes a lot about LLMs, but I find his content to be mostly factual. Much of it is positive, but that doesn't mean it's hype.

It's a protocol. You make payments through your bank app. You can make payments directly, basically a bank transfer, or through a QR code.

The whole idea is that we need a definition that everyone agrees With. The OSD is what the software community at large agreed, so any licences that claim to be open-source are compared to that.

Yes, 100%. I believe that any new Python codebase should embrace typing as much as possible[1], and any JavaScript library should be TypeScript instead. A type system with holes like this is better than no type system. [1] Unfortunately, ma
