Confirmed; and it would also make sense to have rad and deg as options for
the phase. I'll formulate an issue right away.

Can you send example code, please?

Regarding 1), if you write 1/3, then Python converts this into a float
before it is handed over to sympy. To prevent it, you could import S
(Singleton) from sympy and write S(1)/3.
dexpr_dx = se.Derivative(expr, x, 1).xreplace({y*(x**2 + (-S(1)/3)*y**2) +
(-S(1)/2)*x**2 + (-S(1)/2)*y**2: V(x,
Hmm, the last column of your martrix is zero, so it cannot be inverted
because its determiant (e.det()) is zero. So how would Mathematica be able
to calculate an inverse?

In SymPy, str() is meant to be copy-paste-d. See
