If using unix, you should have readline available.
See the tutotial appendix:-

if os.access( path, os.F_OK):

See also os.stat(path) for further info. about a file or dir.

The python help function does not use python23.chm, which is a windows
only help file. You must open it from a menu item or the desktop
explorer. It does contain an entry for "and".

Other platforms usually have documentation in html format, which is why
you get a confusing error message.

You might want self.sex = newsex and return self.sex here.

See __slots__ and PyChecker for possible ways to avoid misspelled
instance variables.
