Suppose I have a list l=[A,B,C,D] and a pre-defined funcion (I am using sympy.solve_linear_system(matrix,A,B,C,D). I want to evaluate the function without writing in A,B,C,D. I want to do it in terms of the list. Is this possible?

When I use Unpack (*list) it gives me A B C D and not A, B, C, D and the function has an error.

    use unpacking, ie `*`. `sympy.solve_linear_system(matrix, *l)` – Ibrahim Apr 17 '22 at 04:49

  • @JakeMcNaughton please add the full traceback and the code which causes this error, so it can be reproduced. [eg](https://stackoverflow.com/help/minimal-reproducible-example) – Ibrahim Apr 17 '22 at 05:09
