Python doesn't have pointers
So what is the difference between a python name and a pointer? I'm a bit
fuzzy on that.
What's the difference between a painting of Obama and a living state
Senator from New York?
Pointers are not part of Python. Python is a language specification.
Some implementations may use pointers to implement the binding, but
that's irrelevant unless you're doing something like linking C code to
such an implementation. Some implementations may run on Motorola
processors, but that's not part of the language either. Other
implementation do not use pointers for the binding.
A name can be reached from a namespace, and it in turn is bound to an
object. That binding is a one-way connection that lets the interpreter
find the object, given the namespace and the name.
