[x3d-public] Thoughts for x3d.py str() calls

[John Carlson]

I’m guessing I can override float.__str__() and maybe the list.__str__()
methods.  Do I do that in x3d.py or my code?

I’m on unfamiliar ground and will have to do some testing unless someone
has a definitive response.

I hope this works.  I will run through the smoke tests provided.

I will probably modify the Blender X3DV exporter first, and if that doesn’t
work, proceed to modify x3d.py.  I don’t think it’s a good idea to modify
x3d.py itself.

So far, I haven’t seen anyone replacing the str() function.
