This *is* the "better" and "standard" way to do it. There
are *worse* ways to emulate C/C++ if you want, but it takes
being *more* obtruse. Because certain objects are mutable,
nothing[*] prevents you from doing something like
x = 
which will return that you've added "42" to your list.
However, it's ugly and relies on side effects.
They Python way (that you deride) is much clearer. Your
input goes in the parameters, and your output gets assigned
the way functions are intended to work. Unambiguous.
I don't expect to call a sine function, and get the result
in the parameter; rather I expect to get it as the result of
the function. Okay...unless I'm working in Assembly
language (but that's one of many reasons *why* I choose
Just a few thoughts,
[*] nothing other than being given dirty looks by folks
reading your code...
