I’m creating a script in the Python SymPy library and am trying to access the result returned by solveset() and linsolve() functions. My problem is that the object returned by these functions is of type finiteset, and I want to select some results automatically to reenter it in other equations. How can I fix it? An example: I create a list of equations with two unknown variables: >>> a1, a2 = symbols('a1, a2') >>> eq2_1 = Eq(-3*a1/10 - 3*a2/20 + 1/12) >>> eq2_2 = Eq(-3*a1/20 - 13*a2/105 + 1/20) >>> lista = [eq2_1,eq2_2] >>> str(lista) [-3*a1/10 - 3*a2/20 + 1/12, -3*a1/20 - 13*a2/105 + 1/20] Then a solve it with the linsolve() method. >>> a = linsolve(lista,a1,a2) >>> a {(71/369, 7/41)} The result is correct, but I'm unable to get these results in to a variable. O tried dics, lists, tuples, indexing commands, but always return the error. "Finiteset objects has no attribute 'command'" Continue reading...
