Interesting. So in your view, a string object representing zero characters is "an", but its length is "the"? I'd have thought that both are considered value types, where identity is immaterial. Thanks for all the insights, all. This is a curious point of English and one that I've definitely seen people on both sides of. My apologies for not responding earlier or to individual posts. For a while (and I'm actually not certain that this post will make it), all Gmail addresses have been unable to post to python-list, and even contacting the list-owner wasn't possible.
