I really hope that sympy would improve to a point where I could use it. But as long as Fourier transforms are as badly broken as they are (see e.g. issues [1], [2] and [3]) I can't use it. And the fact that it doesn't fail or crash but gives wrong answers doesn't inspire much trust. 1: https://github.com/sympy/sympy/issues/2803 https://github.com/sympy/sympy/issues/2803 2: https://github.com/sympy/sympy/issues/7178 https://github.com/sympy/sympy/issues/7178 3: https://github.com/sympy/sympy/issues/18136 https://github.com/sympy/sympy/issues/18136
