it's worth mentioning that Haskell has tuples of length 0, 2, 3, ..., but no tuples of length 1. Tuples are meant for putting n values where 1 value is expected, and when n=1 you just put the value there.
To elaborate on that a bit, the length of a tuple is part of its static type in Haskell. It's impossible to write a function that takes a tuple of arbitrary length -- a function taking a 1-tuple could only ever take a 1-tuple, so it might as well just take the value directly. Things are different in Python -- functions can operate on tuples of varying lengths, so if 1-tuples didn't exist some things would be a bit awkward. Not sure what bearing this has, if any, on the indexing problem. -- Greg _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/WIVEONL3NIY5XPJL5NZPCU4TZ5NAQRSZ/ Code of Conduct: http://python.org/psf/codeofconduct/
