[Visualpython-users] small "feature" request

[<ajs...@op...>]

The fact that the VPython vector object has no __class__ attribute seems inconsistent with the current status of Python objects.Happens that it is creating a practical problem in something I am attempting.

The issue is illustrated as  follows:

>>> from visual import *
Visual-2003-03-15
>>> lis = [1,2,3]
>>> tup =(1,2,3)
>>> vec = vector(1,2,3)
>>> lis.__class__
<type 'list'>
>>> tup.__class__
<type 'tuple'>
>>> vec.__class__
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in ?
    vec.__class__
AttributeError: __class__

If I am not mistaken, the __class__ attributte of lists and tuples did not exist at the time VPython was originally written.  So at that time, it was consistent.  The change I have in mind would, I think, bring the vector object more in line with the type/class unification scheme to which Python has moved.

I have not - at this point - looked at the VPython code in this regard.  But assume it is a minor patch.

My problem is, assuming that I can do the patch myself, I need to know that what I am doing using it  will ultimately work with the official distributiion.

So.....
