Here is SJulia https://github.com/jlapeyre/SJulia
sjulia> f = (x^y + y^z + z^x)^3 (x ^ y + y ^ z + z ^ x) ^ 3 sjulia> f = (x^y + y^z)^3 (x ^ y + y ^ z) ^ 3 sjulia> g = Expand(f) x ^ (3 * y) + 3 * (x ^ (2 * y)) * (y ^ z) + 3 * (x ^ y) * (y ^ (2 * z)) + y ^ (3 * z) SJulia is very close in spirit to Mathematica (Wolfram). This is more or less a language written in Julia, although it can be made to communicate well with Julia. From the user's perspective, there are advantages and disadvantages to implementing symbolic capability as an extension to languages like Julia or Python rather than as another language. I think it is possible to have a language that supports both. Also, CAS can describe various software tools that are designed to do very different things. For instance, a CAS may be intended to implement more or less mathematical rigor. It may have a hierarchy of computer language types meant to represent mathematical objects. Or it may (like Mathematica, Maple, and Maxima) be based on 'expressions' that are essentially devoid of meaning. All of these distinctions, particularly the latter, regarding purpose, are typically confused in discussions on internet fora. I think that Julia is a great language for symbolic computation.
