It's also rather less necessary to use references in Python than it is in C et. al.
You use nothing but references in Python, that is the reason why if you assign a mutable to a new name and modify the object through either name, you see the change through both names.
Perhaps it would've been better for me to say that the sorts of problems that are solved by (pointers and) references in C/C++ can be better solved in other ways in Python...
One can take the position that every variable in Python is a reference; the semantics work out the same. But I find it clearer to view the Python model as conceptually distinct from the "classic" value/reference model. Re-using the old terms is likely to lead to making mistakes based on inapplicable presumptions.
