Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:
I am attaching a patch that expands the documentation of isalnum, isalpha, isdecimal, isdigit, isnumeric, islower, isupper, and isspace. I did not change isidentifier or isprintable because their docs were already complete. I also left out istitle because I could not figure out how to deal with the confusion between Python and Unicode notions of titlecase.
I would also like to note that it appears that isdigit and isdecimal imply isnumeric, so s.isalnum() is equivalent to all(c.isalpha() or c.isnumeric() for c in s). However the actual code does have redundant checks for isdecimal() and isdigit(). I think the documentation should reflect what the code does for an off-chance that someone would replace unicodedata with their own database with which these checks are not redundant.
