Chris, when I execute your code I get the error: TypeError: sympify() got an unexpected keyword argument 'rational'.
I installed sympy using apt-get install python-sympy and synaptic reports 0.6.7-1.1 as the installed version. When I execute ?S I don't see any options for rational. Call def: S(a, locals=None, convert_xor=True) The same is true for nsimplify(2.3, rational=1) from sympy import nsimplify nsimplify(2.3, rational=1) TypeError: nsimplify() got an unexpected keyword argument 'rational' Again executing ?nsimplify mentions no rational param. Definition: nsimplify(expr, constants=[], tolerance=None, full=False) Any ideas?
