I am trying to do something with sage that I found on the internet for
Mathematica. I am trying to extract longitude and latitude values
from google earth as seen in this blog post.

The pythonic way to do this would be:
a = [1,2,3,4]
a.remove(4)
print a

Why? This is a python thing. Generally, if you change an object, it
just changes the object and nothing is returned. .sort(), .append(),
etc. are all consistent this way.

Thanks, Burcin. I tried using a string rep, but it still evaluates in

This problem (+ another problem that I did not describe) has been
solved in alpha.sagenb.org.
Verified with both Safari and Firefox browsers.
Thanks for your efforts!

You can set the SAGE_BROWSER environment variable before you try to
view the plot. For additional information, you can look at the source
code of sage.misc.
Probably depends not on Sage but on your OS. Customize file
associtations in your file manager. Or what aoubt to save picture in
native format and use convertcommand to convert into gif or anything
else.

Dear List,
I'm trying to substitute various expressions for the variables of
symmetric polynomials returned by
SymmetricFunctionAlgebra_generic(...).expand() but I can't figure out
how to ask Sage to replace these variables or coerce them to some
other polynomial ring. E.g.:

Here is an example:
sage: G.=GF(2^8)
sage: M=random_matrix(G,2,2)
sage: map(int,M.row(0))
[152, 58]
sage: map_threaded(int,M)
TypeError: base_ring (=) must be a ring
Why won't map_threaded work where map does?
Thanks,

Hi all,
when I use sage.4.0.2 to plot a picture, it use the eog
to show it in default. But the eog can't save a gif file.
so I want to know how to change the default config of
sage to show something like a picture or a dvi file, etc.
Thanks in advance!

The underscore signifies subscript, the circumflex signifies
superscript. There are some rather baroque rules about getti

Not right now, sorry.
I have an idea how to "hold" symbolic expressions so they are not
evaluated automatically, but it
