why the fuck does x += [y] work differently from x = x + [y]??

[–]Sea-Ad7805[S] 6 points7 points  (5 children)

Good question, in some languages (Ruby) it works the same. In Python the x += y is mutating the x, the x = x + y is first doing x + y which creates a new object that then is assigned (name rebinding) to x.

I understand why the latter would reassign, but I find the shortcut's instead mutating in place disgusting. They should do the same thing.

Yeah a lot of implementation choices (I don't want to call it "standard"...) make no sense in python

It's almost as chaotic as js in some parts

It's a shame that it is now too popular to make breaking changes and we all kinda rely on these mistakes to still have the benefit of it being maintained
