Use the type() function (which is the constructor for the type 'type')
to dynamically create classes (i.e. types), e.g.
In [1]: typ = int
In [2]: number = 3
In [3]: MonoList = type("MonoList", (list,), dict(item_type=typ,
item_number=number))
In [4]: ml = MonoList()
In [5]: ml.item_type
Out[5]: <type 'int'>
In [6]: ml.item_number
Out[6]: 3
In [7]: isinstance(ml, list)
Out[7]: True
