function arguments

[Curbie]

Are arguments passed to functions passed as data or a reference to data or does Python make that call behind the scenes?

All arguments are passed by object reference. In CPython it means concretely that for each argument, the memory address of an existing Python object is passed for each argument (these objects are implemented as C structures).

Thanks Gribouillis,

It was just for the sake of my mind's eye visualization.
