I got both error by both these expressions ,wonder is this a bug or not ?

Hi everyone,
Just a quick announcement: Last week I made the first release of an
open-source package called Combi. It's a package for doing combinatorics in
Python.
Combi lets you explore spaces of permutations and combinations as if they
were Python sequences, but without generating all the

OK, I'm not sure if that counts, because it's from the standard
library.
While we're talking about changes for 1.0, how do people feel about
dropping Python 2.6 support. I think we decided that we need to keep
Python 3.2 support for the time being because of Debian, but what
about 2.6? According to

I'm proposing two things:
1. We maintain the release notes within the source code repository.
2. We institute methods requiring change log notes to be included with each
PR (minor things can be exceptions with minor being subjective).
Here are my reasons for both:
1. When dealing with

Unfortunately, this doesn't work:
#2782 - not mentioned
#2927 - fixes #7145
#7300 - small change, but...
#2992 - two bug fixed
#7296 -
If I'm not mistaken, both Python and scipy keep their docs in a separate repo.
Another challenge with our release notes is that we tend to have a
*lot* of changes per release, thanks to both the rate at which we
release, and the large amount of code we have coming in from GSoC

Hi,
I only am realizing that I cannot do FiniteSet[1, 2, 3, 4]) any more.
I did find it very useful to create a set from the elements of a set.
Anyway, it's probably way late for that.
So, what is the recommended way now to create a FiniteSet from an
existing list or any other iterable?

This was an intentional change. The previous way made it impossible to
create things like FiniteSet(FiniteSet(1, 2, 3)) (a set containing a
single set).
