I think this is due to a poor definition: the decision was made that
variables are named

Of course they are. So mathematically speaking everything is fine.
However, unless there's a good reason for Set(['a', 'b', 'c']) to
result in {'a', 'c',

This is a bit disconcerting:
sage: Set(['a', 'b', 'c'])
{'a', 'c', 'b'}
sage: Set(['a', 'b', 'c', 'd'])
{'a', 'c', 'b', 'd'}
sage: Set(['a', 'b', 'c', 'd', 'e'])
{'a', 'c', 'b', 'e', 'd'}
Bug? It doesn't seem to happen with lists of numbers.
Best,

Someone reading a tutorial I wrote on cython was quite confused
because the header "%cython " in a cell gives a confusing error, and
needs to be "%cython". It seems to me that the extra whitespace
should not cause such problems, and this is a bug. Anyone disagree?

I think I sent this from the wrong email address last time, since I
don't see it on google groups. If you already got this I apologize.

Hello everybody !!!
I recently asked a question here : I have a set of points in R^n (or
C^n, or any vectorial space for the matter..), to which is associated
a set of values. Said differently, I have a function whose values I
only know at several points. I then would like, given a degree d, to

Maybe this is done to handle the case where "sage-main" is a symlink
to an actual directory. The option -L means to copy symlinks as real
files. Otherwise, the symlink may be copied (when

Whilst computing things like 1+1 work fine in command line mode, they do not

Hi William,
I just skipped over the Mac OS X "tools" page from the R project:
http://r.research.att.co
In the past there was discussion about "automatic uploading" of sws
files and such on local servers so that double clicking an sws file
would do the right thing.
See for example here:

In my recent attempt to create a binary distribution for Solaris (see thread
"What directories should go into a binary distribution?"), failed as the '-a'
option was used to the 'cp' command in
