Python is pass-by-value. It's just that all values are implicit "pointers". Much like Java except without a distinction between primitives and objects. > Sometimes I wish to work with "copies", in that when I pass in an > integer variable into a function, I want the function to be modifying > a COPY, not the reference. Is this possible? Typically, there's no reason to make a copy of an immutable object. But if you want to copy things, take a look at the "copy" module. -- http://mail.python.org/mailman/listinfo/python-list
