what is a boolean trap? (programming antipattern) (beginner - intermediate) anthony explains

Why not just define two functions - pop_first and pop_last?

[@anthonywritescode]

that would work well too!

I am waiting for the sequel: "what is a troolean trap?" 🤣

cool video

Is there an advantage to using an Enum over typing.Literal?

[@marco_gorelli]

Do you know if there exists a tool to detect boolean traps? e.g. flake8 extension, or even a tool to re-write them. If not, I'm tempted to try writing one

[@anthonywritescode]

not that I know of! but it'd be pretty easy to detect if the codebase uses type extensions (non-namedonly bool parameter) or a call which takes a boolean literal in a positional argument

[@420_gunna]

I haven't seen someone use the enum.Enum constructor like that before -- I usually see people write a class that inherits from Enum, then defines a bunch of class attributes like Tomato = "TOMATO", Lettuce = "LETTUCE", etc. Is using the enum.Enum primary constructor directly (like enum.Enum("Tomato") the same as writing a class that inherits from Enum with class attributes like Tomato = "Tomato"? I really need to look at how enums actually work under the hood :)

[@anthonywritescode]

it's a bit magical -- acts as both a metaclass and a callable

[@teslainvestah5003]

I'd assume dct.popitem(True) would pop (3,4). Because if a method called popitem takes any argument, it should be an integer index.
In my projects I just have unlimited line length, and never use positional arguments for anything unless some module (often pygame) forces me to.

[@anthonywritescode]

True is an integer, checkmate athiests

[@darrenlefcoe]

great video, but why write code in terminal as opposed to a lightweight editor like vscode which is easier to do ?

[@anthonywritescode]

"vscode" "lightweight" lmao

[@darrenlefcoe]

@@anthonywritescode fair enough. Just thought that some linting and intellisense might be helpful.

[@anthonywritescode]

implying I don't have linting?

[@darrenlefcoe]

@@anthonywritescode respect to those who can operate without those tools...
