Enums Explained In Under 12 Minutes In Python

In today’s video we’re going to be learning about the basics of enums in Python. We will also be covering what a Flag is and how to use the auto() feature.

FYI 9:04 it auto completed to black instead of blue.
Interesting video. Thanks

python doing bitflags is nuts as heck. super awesome! i am ready to use it

Flag works like:
RED = 1 (001)
GREEN = 2 (010)
BLUE = 4 (100)
ALL = 7 (111) because 001 | 010 | 100 = 111

I came here thinking "ok, already know about enums". Then I just discovered Flag class. Awesome video. Thanks!

Very good and clear explanation of enums, especially flags. What I'm missing is:
- getting the value and the name of the enum constant (either one is sometimes useful e.g. in printing the selected value, logs, converting the selection to, let's say, SQL query),
- StrEnum type (if the enum constants have to be strings, it's easier to get the string value out of StrEnum than an Enum),
- iterating over all values of an enum type (useful e.g. with GUI constrols, like a dropdown).
But overall, a very good introduction.

I was just planning to dive in to Enums thanks man

i knew about Enums, but not about Flags ! Maybe i really should check the whole documentation of the enum package, it seems it haven't revealed all its best secrets yet !

This is a cool feature. I usually just create a module that contains a bunch of constants in cases like this. I think I'll start using an Enum class instead.

please do one video on how to dind difference between instance and library vs package vs module

[michaelhoffmann]

I find I use StrEnum with auto() somewhat frequently, though its usefulness some would debate. It's nice to have one clear place to replace a string, rather than having trust my IDE to do a find/replace exactly where I want it.

As someone leaning python I'm slightly confused what use cases you would use this for. Can someone give hypothetical use cases for this function?

[vegameta]

а для чего делать наследование от Enum для строковых значений? для таких случаев имеется StrEnum

Is boolean actually an Enum with 2 constants?

[marionowera]

I think you shouldn't use str as type hint to enum members?

[ppgiga]

I literally looked this up yesterday...

For those watching: please don’t use f-strings if you aren’t going to use the functionality of f-strings. Readability comes in to play here due to intent

You forget the IntEnum which makes it quite useful to be stored as an integer constant directly into the database.

Thank you for finding us this info...However, Is enum really essential ? I am not able to comprehend why would it be needed ? Just for cleaner looking code ?

Hey man, this video is great! I cant stop hearing you talk about Colas tho lol.
Color is pronounced CUH-ler in the US and CUH-luh in the UK
Thanks for the tutorial!

so a Flag is acting as a bitmask which can be used for assigning multiple states while an Enum is better for exclusive states.
