 * [[http://matplotlib.sourceforge.net/basemap/doc/html/]] Matplotlib Basemap

To enable Basemap (on ZMAW Linux ia32/x64 and solaris10) you have to type before starting Python2.4.4:
{{{
module load Python/2.4.4
}}}
or to start Python2.6.2 (recommended):
{{{
module load R/2.7.0
module load Python/2.6.2
}}}

In Python you can import the Basemap module by
{{{
from mpl_toolkits.basemap import Basemap
}}}

=== 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
}}}

=== Installation in the home directory ===
The seawater module is installed on the ZMAW machines for Python 2.6. Use
{{{
module load Python/2.6.2
}}}
to set up the environment. In the following it is explained how to install the module for the case if it would be not available or if a different version of python has to be used.

Installation of module {{{seawater}}} in directory {{{~/modules}}}
{{{
python setup.py install --prefix=~/modules/
}}}

Usage
{{{
import sys,os
home=os.getenv('HOME')
genpath=home+'/modules/lib/python2.4/site-packages/'
if not sys.path.__contains__(genpath):
    sys.path.append(genpath)
