#Here is the Python code you requested.

class Array:
    "Una clase minima para algebra lineal"    
    def __init__(self, list_of_rows): 
        "Constructor"
        self.data = list_of_rows
        self.shape = (len(list_of_rows), len(list_of_rows[0]))

A = Array([[1,2,3], [4,5,6]])
A.__dict__ # el campo escondido __dict__ permite acceder a las propiedades de clase de un objeto

A.data

A.shape
