This could lead to issues if you use the auto for choices that you are gonna store in a DB, and later on the code changes and different integers are now mapped to different "constants"

[megalodon]

Very nice, I really like these kind of videos. Thanks!

[treblaoj]

I like this kind of video, there are quite engaging and give info in direct way

[kcvinu]

That's a solution for my headache. Often, I need to re arrange my Enums. At that time, it's quite difficult to delete the current value and add new values.

[stradivari]

I also find inheriting from both (str, Enum) quite useful

[JorgeLuis-tsqp]

It's important to notice that the result is not the same in both cases as auto() sets the first element to 1, range() will set it to 0.

How about with powers of 2 so that the CEO could also be President?

[nowyouknow]

Cool but the first way is more readable.

[lawrencedoliveiro]

I like to capitalize the enum class name as well.

[rungxanh]

It seems a bit less readable compared to the original implementation. However, nice tips 😊

[typinowly]

You need to be careful here, if you ever serialize the enum object (safe to a database or file for instance). It will likely use the number, not the name (depending on how you serialize). When inserting new options without explicitly asigning numbers, the serialized data might be interpreted differently, after you load them back into your program when you autogenerate the numbers.

[johnaweiss]

the code is so tiny it's almost unreadable. But i can see the narrator so well!

[aesp]

i don't understand what the point of an enum is if you just have to assign another variable to it anyway, then use a special function to extract the value. variables give you the value immediately. i know i'm missing something but i swear enums have always seemed useless lol.

[gadeichhorn]

Enum should be fixed. If you use dynamic numbering you may run into issues when client code relay on a value.

[Empristis]

is it wrong if I give str values instead of numbers to my enums?

[MagnusAnand]

Mmm… It should be super explicit.
Why use auto or a range when you have four fields?
And if you have more, having an automatic number assignment just complicates the code IMHO.

[ChrisBNisbet]

Hmm, so Albo wants to replace FF generation with 'renewables' aka unreliable.
Has he figured out how many wind turbines would be required to do that? How many wind turbines would you need to supply the required electricity when the wind isn't blowing?

[Efecretion]

Why use a class for an enum? Why not a dict? Serious question btw.

[jacobshore]

Assigning enums as 0 is an antipattern
If you don't want Role.CEO to be Falsy.
