The first killer app for Python was running Fortran code from within 
Python. People use Python for both pre- and post-processing. For small 
jobs, this enabled running Fortran interactively.

This lead to Numerical Python, now Numpy, SciPy, and later Sage and 
other scientific and Python packages. I believe SciPy has an f2py 
(fortran to py) module to help with running Fortran under Python (but it 
has been years since I read the details).

Detailed questions might get better answers on, for instance, a scipy list.
