It seems to me that Guido's version is easier to teach, and more useful.
Easier to teach, because one can present this as the argument's "default
value" being string.whitespace; more useful because I more often have strings
to clean up that may end with arbitrary sequences of "junk" characters I want
to remove, rather than with a potential specific "junk" word (and the latter
case may be easier to handle with an .endswith test). Admittedly the
specific use case which Guido recently mentioned (cleaning up, if present,
the trailing 'L' from a number's repr) is handled just as well in either way,
since it's only one character. But say e.g. I receive datagrams that may or
may not end with trailing \r , \n, or \r\n -- .rstrip("\r\n") in Guido's
version immediately solves my problem. I can't think of a similarly generic
use-case for yours (perhaps a failure of imagination on my part).
