This reflects a key misunderstanding of how Python works -- a ndarray (
or any python object) does not "have a name".
when you write:
you are creating a ndarray object, and _binding_ the name "index" to it.
the object exists apart from it's name:
now there is a an andarray object in the list -- but it has no name. You
can also bind multiple names to the same object:
fred = index
john = index
now "index", "fred", and "john" are all bound to the same object -- what
would be its name now?
Hence Olivier's suggestionss -- al various ways to store and refere to
objects -- binding to a variable is only one way.
This is a good read that should clarify it all:
