Magic Numbers sind Zahlen (oder auch Strings), die irgendwo im Code „einfach so“ stehen und deren Bedeutung man nur errät. Du siehst dann `60`, `3`, `1024` oder `"admin"` und musst aus dem Kontext heraus rekonstruieren, *warum genau dieser Wert* dort steht. Zahlen im Code sind nicht per se schl

Modern Enums Battle: Python 3.10 vs PHP 8.1!

Both languages just added enums! Python's Enum class vs PHP's native enums - which implementation wins? This is HUGE!

For the gophers out there... Just a reminder: a bunch of consts + iota isn't an enum. Slugs aren’t enums. Interfaces, structs, and switch statements aren’t enums either.

Enums are enums.

Scala went through the same BS for what felt like a gazillion years.Just add a proper enum to the language. Go really needs a proper sum type. Don’t wait until Go v3 like we did in Scala.

"Simplicity" here is creating extraordinary levels of complexity.

Constants or Enums in PHP?

🔹 Constants = silent bugs
🔹 Enums = strong typing, cleaner code

Your future self will thank you.

Dear #lazyweb, what is the best way you know to represent #tagged #enums in #Python? It needs to be at least somewhat type-checkable, although it's possible I might settle for something like enumerating each value's associated data type/tuple once again for mypy to see.

So far I've been using a hierarchy of frozen dataclasses and then a single-dispatch handler; however, now I have a possible use case with the need for validation, and the hierarchy of dataclasses is not discoverable, thus not, well, enumerable :)

I really, really like the django_enum package.

Imagine Django's TextChoices/IntegerChoices classes, but with the ability to encapsulate any additional information for each choice in one place.

I don't use it everywhere, but it's super useful in a number of use-cases.

Here are a few places where I've found django_enum makes things easier. See alt text for more detail about how I use of each of these.

Fascinating that #TypeScript 's people are talking about getting rid of #enums (union types can handle most of the situations - someone recently wrote they consider TS enums a mistake), yet now we have #Javascript talking about putting them in JS using the TS syntax:
