Python scope and parameter passing method

[Jose Saias]

Hy 


I'm a portuguese student and I am comparing Python to Objective C. Can
some one help me in this?


I would like to ask you about Python:

- the parameter-passing methods (call-by name/value/reference);
- dynamic memory control (garbage collection?, allocation for activation
records);
- the scope of a name (lexical/dynamic);
- innermost or outermost evaluation;
- a small example program that explores the language possibilities.


I appreciate your help!
