Scientific Programming with Python
Documentation
Modules for Scientific Computing and Visualization
SciPy/NumPy
pylab
Matplotlib/pylab Plotting functions with a high degree of Matlab compatibility
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
GDAL
GDAL - Geospatial Data Abstraction Library for various satellite data formats
To enable GDAL use
module load gdal
from osgeo import gdal
PyNGL PyNio
PyNGL/PyNIO Python interface to NCAR Command Language
- Scientific visualization and data formats (netCDF, HDF, GRIB etc.)
To enable PyNGL (on ZMAW Linux ia32/x64 and solaris10) you have to type
module load PyNGL/1.2.0
Please note, that Nio should be on the top of the list, e.g.
import Nio from osgeo import gdal import pylab as pl
Python Interface to GrADS
RPy
RPy (R from Python) Statistical computing and graphics
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
endRun f2py -c -m hello hello.f
Now in IPython try:
In [1]: import hello In [2]: hello.foo(4) Hello from Fortran! a= 4
Example taken from
Topical Modules
Seawater is a package for computing properties of seawater (UNESCO 1981 and UNESCO 1983).
Escript/Finley: Fast Finite Elements for Partial Differential Equations
More topical software can be found at http://scipy.org/Topical_Software
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)
from seawater import *
