Strangely enough, I'm lazy enough to not check the source too :-) Actually, more to the point, I don't read C, so even if I did check the source, I wouldn't know what it was trying to tell me. > However, the doc [1] warns you about such comparisons: """Most other > types compare unequal unless they are the same object; the choice > whether one object is considered smaller or larger than another one is > made arbitrarily but consistently within one execution of a program.""" I am aware of that. That's a wart. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
