Hi,
See this:
sage: R.t=PowerSeriesRing(QQ)
sage: P.x=PolynomialRing(R)
sage: f=(x*t+t^2)/t
sage: f
x + t
sage: P(f)

Dear all,
I noticed that some of my old code does not work any more with sage
4.0.
I used to assign the solutions of equations by referring to them in
the following way:

A comparable case works well.
sage: S.x=ZZ[]
sage: f=2*x+4;
sage: f/2
x + 2
sage: S(f/2).parent()

This is more of a python question than a Sage question, but

new lists, each of which is obtained from the original list by

Hi Alasdair,
I understand that you mean
sage: lst=[[1,2],[3,4],[5,6]]
sage: for x in lst:
: lstc=copy(lst)
: lstc.remove(x)
: print lstc
:
[[3, 4], [5, 6]]
[[1, 2], [5, 6]]
[[1, 2], [3, 4]]
Probably you got onle None printed. This is because the

confused.

FYI, the Python site has plenty of documentation; the Library
reference manual would have provided the answer.

You might have to use vmware workstation in order to configure the

It costs money, but there is an easy 1-month free trial. You could try
that in order to tell whether multiple cores will work with the

Here's a really dumb thing you could do.
(1) Make a copy of sage-vmware-* to another directory.
(2) Run both vmware's at the same time.
That'll definitely use both cores on your computer.
Indeed! That's what I ended up doing this afternoon. I had VMWare
