defining an already exisiting numpy array within a class

Question

I am creating an object in python. I have a numpy array from an H5 file that I would like to define within it. The numpy array is coordinates. I was poking around online and found tons of information about creating numpy arrays, or creating objects in numpy arrays.. but I can't find anything on defining an already made numpy array inside an object.

class Node(object):
    def __init__(self, globalIndex, coordinates):

        #Useful things to record
        self.globalIndex = globalIndex
        self.coordinates = numpy.coordinates

        #Dictionaries to be used
        self.localIndices ={}
        self.GhostLayer = {}

My question: is there a specific way to define my numpy array within this class? If not (the fact that I couldn't find anything about it makes me think that it can't be done), how else could I import a numpy array?

Why are you using numpy.coordinates? just use coordinates. — Amr

Will that recognize a numpy array? I assumed there needed to be some way to denote a numpy array. — Ason

Python is a dynamic typed language, variable names don't have to know anything about the objects they point to, so as long as coordinates is a numpy array, then that's what your new variable would be. — Amr

Thank you for your explanation and patience. I appreciate it. I wish I could have given you points for your answer. — Ason

No problem, you should also learn about Namespaces or variable scopes in Python. — Amr

class Node(object):
    def __init__(self, globalIndex, coordinates):

        #Useful things to record
        self.globalIndex = globalIndex
        self.coordinates = coordinates # now self.coordinates is just another name for your array

Assuming n = Node(some_index, numpy_coordinate_array_name)
