Simon,
You can start a container and open a shell on it via:
docker run -it image_name /bin/bash
The container will keep running until you exit the shell, if not longer.
You can open a shell on any running container via
docker exec -it container_name /bin/bash

That semicolon gives you the syntax error, but correcting that only
exposes a runtime error. You should look at what your x is in the
loop.
If you write "for x in range(len(l1))" you are a little closer
already.
if l1[x:x+Integer(1)]==l2[x:x+Integer(1)]; <== should be colon, not
semicolon
Why not be more Pythonic?

Thankx for your quick response!!!
I wish I could help, I'm weak in programming... specially in c++, but
I'm trying to learn as fast as possible (~10 years according to Peter
Norvig)...
Anyway I will try a little bit.
About extension fields, do you mean GF(p^w) where p is prime? I though

This works.

m1 = 0.33;
m2 = 0.39;
sap = 1.2;
saf = 0.4;
H = 10;
E(t1,t2)= -1*m1*H*sin(t1) - m2* H * sin(t2)+sap * cos(t2-t1)-saf * sin

You might also find some of the differential equation interact
examples helpful, there are three that relate to Euler's method:

Just FYI, this is changed in the new Pynac package (0.1.9) which will
most likely end up in Sage 4.1.2. It's not clear to me when this
changed -
wow, Iwas trying to figure out how to do exactly what you did, but I
don't know how to program.
Thx, now I have something to base myself off.

You could try
x,y = var("x,y")
dy_dxB(x,y) = cos(x) - sin(x) - y
eulers_method(dy_dxB,0,2,0.1,3)
but I don't know why Sage will not evaluate the cos and
sin terms, so you end up with a long messy hybrid
symbolic/numberical expression.
If you use instead
eulers_method(dy_dxB,0,2,0.1,3, method=

Perfect ! I pass the edited buffer to sage-mode in emacs,
get then a new sage-send-region,
If you simply copy-paste into the sage commandline, you will get that error
since after the `return(1)` line, indention goes back one level, like so:
sage: def ff(n):
:if n == 0:
:return(1)
:else:

They're only auto-generated because I put code in builder.py to do so.
