He doesn't have to write it, as it is very obvious, that no Python code

Fortran or C. Look at this:
There is one big proviso. The C or Fortran needs to be well written
It's seriously hard to write computational Python code that is faster
than C code, though.
Agreed, it was the assertion that "no Python code on earth...stands
a chance..." that I was objecting to.
There are many areas where the C code would have to be pathologically
bad to be beaten by Python, but there are plenty of places where only
slightly inefficient C code can be competitive relatie to Python.
Maybe there're those areas, but the top posters question is about
reimplementing BLAS, which is a highly optimized package for linear
algebra. And in this area no pure Python code on earth on any currently
available Python implementation stands a chance performance wise to one
of the C or Fortran implementations.
