Which I suspect is necessary.

That's something I've learned to figure out about any new language I 
pick up -- if parameters are passed by value or by reference, and 
secondly how to invoke a function appropriately for my specific use case.

Unfortunately, there are issues determining if python is in either camp, 
which certainly leads to confusion. see 
http://www.python-course.eu/passing_arguments.php or google "python pass 
by value or reference" for more examples.
