Numpy is partly written in C but includes a lot of Python code. If you include scipy or scikit learn or pandas, most of the code is python calling primitive numpy C operations. I'd expect that many semi-complex data science programs to benefit from improvement in the python interpreter, especially if they weren't written in super tight numpy code.
