Yes, Python doesn't have types at compile time, only at runtime. Which has advantages for easy prototyping etc., but based on my experience, if I want to understand other people's code, it really helps to know the types that go into methods/functions. As a side effect, also powerful IDEs can be built around it, as you mentioned. Also, you don't need to write tests just to check syntax like we have to do in SymPy, because the compiler checks it for you. The only problem with C++ that I have is that it takes forever (for me) to write something in it (compared to Python) and it is a complex language overall. But I am convinced that it is worthy for symbolic manipulation library. > Regarding the Rubi ruleset, I think that a pattern matching improvement and > rewriting in C++ would be needed, but one has also to improve the > assumptions module in order to be able to perform the same checks as in > Mathematica, besides the checks are to be inserted inside the pattern > matching algorithm. Exactly. CSymPy currently has no assumptions, so those would need to be added. Based on my discussions so far, I think this should be what I should work on next in CSymPy --- fast pattern matching and assumptions. > It would be very nice to find an equivalent ruleset as Rubi for differential > equations, if there are any.
