Hi,
In the following code a.taylor works both when using load and starting
it with python, b.taylor works with load within sage but gives the
exception when using python. There is no difference when using the
python version from the sage tree.
I removed superfluous python code. The code is the generating function
for a unordered partition.
-------
# be sure sage can be found when using Python
# comment it when starting from within sage with load
from sagePaths import *
set_paths()
#
from sage.all import *
from operator import *
if __name__ == "__main__":
var('x')
a = prod([1/(1-x**i) for i in range(1, 8)])
b = prod([1/(1-x**i) for i in range(1, 9)])
print a.taylor(x,0,5)
print b.taylor(x,0,5)
Result when using python:
5 4 3 2
7 x + 5 x + 3 x + 2 x + x + 1
Traceback (most recent call last):

Any ideas?
