Actually I think the correct solution would be to add the line
export SAGE_DOC=$SAGE_ROOT/devel/sage/doc
to the wiki. However python does not complain about any other
directory..

Unfortunately for me there seems to be some awkward unforeseen error
if I run the script suggested in the wiki. Here I have some lenghty
output.. The questions are at the very bottom.

And this is what I get if I call any other python script containing
"form sage.all import"...
Anyhow I've created a script "runsage" to be able to use it in the way
"runsage test.sage" with "test.sage" beeing e.g. "from sage.all import
*". It reads
export SAGE_ROOT=/home/ivan/aps/sage-3.4.1-linux-Ubuntu_8.10-sse2-i686-
Linux
export SAGE_LOCAL=$SAGE_ROOT/local
export SAGE_DOC=$SAGE_ROOT/devel/sage/doc
export DOT_SAGE=~/.sage/
export PATH=$SAGE_ROOT/local/bin:$PATH
export LD_LIBRARY_PATH="$SAGE_ROOT/local/lib/openmpi:$SAGE_ROOT/local/
lib/:"

python $1
But again this results in an error:

My solution is:
If I have sage code, where I do not mind to make use of the sage
interpreter I just write it in sage syntax and run it by "sage
code.sage"
If I want to stay in python, i run it by "sage code.py" and include
"from sage.all import *". This works for me and the code will work for
others who do not have this problem (i.e. can just type "python
sage.py").
My question: If I want to test a function from within a sage session
at the moment i type "import code.sage / code.py" and it runs. Clearly
this is not the best way to do it.. Any suggestions? (Please keep in
mind that "!python .." does not work for me).
