It is irrelevant.
Python calls Python functions by associating argument objects (or
objects derived therefrom) with paramenter names, very much like
assigment statements.
If one understands Python objects, names, and assignment statements,
which one must to understand Python, this completely explains the
function calls, function execution, and its effect on passed objects.
All Python expressions evaluate to an object. Call expressions evaluate
to the object returned by the function.
Different interpreters implement call and return differently. Certainly,
most humans do not use C pointers when they mentally execute Python code.
