Yes. > but no, that's not the case. A single character can titlecase to two > characters, or to a single character that isn't the same as if you > uppercase or lowercase it. See examples in previous post. The document for str.title() states that the initial character of each word is converted to uppercase. My point is that for characters that remain single characters regardless of case that means (to me) that s.title()[0] == s[0].upper() or for a single character string s.title() == s.upper() That's not true for digraphs where there is a third, distinct and different "title" case. I think the doc should state that the initial character is converted to titlecase. A parenthentical statement that titlecase is usually but not always equal to uppercase would be nice, but the current statement is obsolete and not correct in all, um... cases. -- Grant -- https://mail.python.org/mailman/listinfo/python-list
