Comment (by vinceknight):
Replying to [comment:37 kcrisman]:
> > We have implemented a check such that if a user accidentally enters
(1) it gets changed to (1,). Python automatically recognises that A, ==
(A,) anyway as tuples are defined by the commas and not the brackets.
> What I mean is that perhaps the ''desired'' input method should be
without commas. Vince's comment seems good - maybe one could include an
example and then clarify where/when it would be suboptimal to use the
`(1)` notation. I'm not worried about `A,` versus `(A,)` because most
non-Python-gurus are not going to be putting the commas in!
We had a long think about this and have included some text in the
documentation to justify what is happening now. In particular we think
that `A` alone should not necessarily be allowed as we don't really want
to map `A` to a value but the set containing `A`...
Otherwise, pretty sure that we've addressed everything else you raised.
> >Thanks for the comments Karl, busy (with Dana and TJ actually!) right
now but will get those changes done this evening :)
> No rush on my part - I heard from both of them about your adventure this
week. Slightly jealous, but I hope you all have a great time and that
some fruit comes of it!
Not meaning to make you more jealous but it really was a great week, it
was awesome to meet Dana and TJ: they're great! Sadly, I forgot the one in
joke you told me about Dana, I seem to remember you telling me to ask him
about something... Perhaps the next time the 3 of us will be in the same
spot and you could remind me (I realise trac probably isn't the right
place for this chat - apologies) :)
