Modules for Scientific Computing and Visualization

SciPy/NumPy

pylab

To enable Basemap (on ZMAW Linux ia32/x64 and solaris10) you have to type before starting Python 

module load Python/2.4.4

In Python you can import the Basemap module by 

from mpl_toolkits.basemap import Basemap

GDAL

PyNGL

To enable PyNGL (on ZMAW Linux ia32/x64 and solaris10) you have to type 

module load PyNGL/1.2.0

Python Interface to GrADS

RPy

F2PY: Fortran to Python interface generator

Calling Fortran code from python is easy! Create a file hello.f: 

C File hello.f
      subroutine foo (a)
      integer a
      print*, "Hello from Fortran!"
      print*, "a=",a
      end

Run f2py -c -m hello hello.f

Now in IPython try: 

In [1]: import hello
In [2]: hello.foo(4)
 Hello from Fortran!
 a=           4
