C++ is pain, numpy is pain if you need a loop, numba and cython are pain if you need any more complex data structures.
Sadly Julia is pain too if you don't do REPL/notebook (which you shouldn't). Julia has the design to solve the two language problem but not the implementation. And will probably never have because Julia community refuses to see this as a problem.
