ARGGHHHH Python!!! why the hell is this a thing... if I specify a default argument, I want it to be a default argument, not get carried over....

Then use a tuple.

@sbiewald the point is that I wanted to just set a default value for a function. The real solution is to do this (see image)

And the people say js is 🤪

Documentation is our friend.

@AmyShackles agreed. It just took me a while to figure out why my system that's made up of mostly pure functions returned a different number every time I ran it.

@gitoutofhere The code from you comment, won't that allow

func("problem")

@A4Abhiraj so will the original code... But that's expected when a language has no typing.

@gitoutofhere Oh, my bad! From a typed world ;)

Why the hell a function carry it's private variables after the execution. In other languages I would expect "a" to be re-declared and re-initiated 😑

@h4xx3r Function arguments are evaluated once at runtime - it is the same mutable list.

@h4xx3r I think the reasoning is that you shouldn't use a mutable object as a default parameter unless you want to utilize the caching functionality, since default arguments are evaluated when the function is defined, not on every eval.

@sbiewald Agh! Beat me to it.
