As a first step, here is a complete example on Mac OS X of using
the Sage libraries with the stock system-wide Python 2.5.1 interpreter.
Note the crucial use of "sage -sh", which sets a bunch of Sage-relevant
environment variables.
D-69-91-159-216:~ was$ sage -sh
Starting subshell with Sage environment variables set.
Be sure to exit when you are done and do not do anything
with other copies of Sage!
Sage subshell$ export PYTHONPATH=$SAGE_LOCAL/lib/python/site-packages
Sage subshell$ python
Python 2.5.1 (r251:54863, Feb 2 2008, 18:15:25)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sage.all
>>> sage.all.factor(2008)
2^3 * 251
------------------------
If you don't want to use Sage -sh you would have to set several SAGE
environment variables.
One way is by sourcing the script sage-env:
D-69-91-159-216:~ was$ source SAGE_ROOT/local/bin/sage-env #
replace SAGE_ROOT
D-69-91-159-216:~ was$ export PYTHONPATH=$SAGE_LOCAL/lib/python/site-packages
D-69-91-159-216:~ was$ python
Python 2.5.1 (r251:54863, Feb 2 2008, 18:15:25)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import sage.all
>>> x = sage.all.x
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'x'
>>> x = sage.all.var('x')
>>> sage.all.sin(x**2).integrate()
sqrt(pi)*((sqrt(2)*I + sqrt(2))*erf((sqrt(2)*I + sqrt(2))*x/2) +
(sqrt(2)*I - sqrt(2))*erf((sqrt(2)*I - sqrt(2))*x/2))/8
---------------
I hope the above is of some use to you.
