I'll believe it when I see it, because right now there is no alternative. I wrote a piece of physics software recently and sympy (and indeed python in general) was so lacking in features that I had to write half of the software as mathematica packages, half of it as python. I would have implemented those functions myself but they are actually extremely non-trivial and I wouldn't be surprised if just one of the basic…
ran into this myself just today, but with Symbolics.jl instead of SymPy. I just needed an algebra scratchpad, and Symbolics was.. barren. and uninviting. I thought of reaching for Mathematica but resorted to pencil and paper, like a barbarian. same deal with solvers more generally. the coin-or stuff (e.g. Cbc) is slow and buggy, Cplex and Gurobi are far better but very expensive. where are the PhDs in this field? wha…
Have you tried Maxima? It seems more ergonomic.
