In other words, choose the right tool for the job. However I think the OP was comparing dynamic vs static languages. Ey made a prototype physics simulation in Python whose source code was nice to read but performed terribly. Ey then decided to write it in C (not a bad choice mind you). It seemed to me that the OP found the readability of Python (and dynamic languages in general) a useful trait to have while lamenting that their implementations were too slow to be practical for eirs purposes. Therefore I proposed an example of a dynamic language with the property of being easy to read while being fast in implementation. Otherwise I think we violently agree.
