Numeric and Numpy will faster than raw Python for array operations,
but I don't think they will match well-written C or Fortran, because
compilers can better optimize code in those "less dynamic" languages.

Someone recently mentioned here ("Quantum term project code- for
interest and for help") an example where Numeric was 180 times faster
in Fortran 95 using gfortran, asking for advice on how to speed up the
Python code -- see

. No one replied.
