What do you use as symbols for Python ?

[Pierre Barbier de Reuille]

Well, thank you all !

I still feel it could be good for Python to have some kind of symbols
built in, and I will try to expose that to the python-dev list, to see
their reaction.

But in the different solutions proposed, the one I prefer is probably
the definitions of contants in a class to group them. Simple and
organized, I like it.

Thanks,

Pierre
