Hey folks,

I am just starting off in python, but have good knowledge of both Java and C#. Now is the problem that I need to have multiple instances of one dictionary, that is not a problem if you know how many, but now, it is an unknown amount.

Some background info:

I am making a library for an API. This library must be easy to use for the people who are going to use it. So I am making the models for the data, the connections and so on, so they just have to fill in the gaps. In C# and Java I did it with objects, but they do not work alike in python, or at least that is what I have found.

If I do this:

class Item:
    def __init__(self, id, productId, quantity, pageCount, files, option, metadata):
        self.id = id
        self.productId = productId
        self.quantity = quantity
        self.pageCount = pageCount
        self.files = files
        self.option = option
        self.metadata = metadata

itm = Item(1,None,1,1,'asdf',{'asdf': 3, 'ads': 55},None)
print(itm)

it prints: <__main__.Item object at 0x02EBF3B0>

So that is not usefull to me. There can be an infinite amount of objects of Item, and it needs to be easy accessable, just like 
for i in items
    print(i)

and it has to show all the parameters of the class Item and not say "ive got an object  at this memory address, have a nice day"

I hope my question is clear.
