I just looked at Jeremy Hylton's warts posting at http://starship.python.net/crew/amk/python/writing/warts.html

It reminded me that one feature I really, really want in Python 3000 is the ability to declare constants. Assigning to a constant should raise an error.

Is this on the to-do list?

I know this isn't "perfect", but what I do often is have a Constants.py file that has all my constants in a class which has __setattr__ over ridden to raise an exception. This has two things;

1. Difficult to modify the attributes, at least accidentally 2. Keeps the name-space less poluted by thousands of constants.

Just an idea, I think do this:

constants = Constants() x = constants.foo

Seems clean (reasonably) to me.

I think I stole this from the timbot.
