 2. A document that can save the inputs and outputs of the session as well as additional text that accompanies the code but is not meant for execution. In this way, notebook files serve as a complete computational record of a session including explanatory text and mathematics, code and resulting figures.

How to edit python code?

In November 2013, we asked people on our python-friends@lists.zmaw.de mailing list, which editor/IDE is preferred for python hacking. Below is a summary of the anwers:

python specific editors

  • ipython notebook

IDE's

  • pycharm
  • eclipse

advanced generic text editors

  • geany
  • vim (plugins: pyflakes, jedi-vim)
  • emacs (python-mode.el, auto-complete, yasnippet)
  • sublime 2
  • spyder

Generic text editors

  • nedit
  • gedit
  • kate
  • snipmate
  • easymotion
  • nerdtree

Modules for Scientific Computing and Visualization

A good summary webpage how to use geospatial data (e.g. netCDF, GRIB) with python is given here.

SciPy/NumPy

pylab

Import the Basemap module 

from mpl_toolkits.basemap import Basemap

GDAL

PyNGL PyNio

Python Interface to GrADS

RPy

F2PY: Fortran to Python interface generator

Calling Fortran code from python is easy!

Fortran to Python

Topical Modules

More topical software can be found at http://scipy.org/Topical_Software

Python and Climate

Python and Weather Satellite Data

IPython Notebooks

A notebook is a combination of two things:

  1. An interactive session connected to an IPython kernel, controlled by a web application that can send input to the console and display many types of output (text, graphics, mathematics and more).
  2. A document that can save the inputs and outputs of the session as well as additional text that accompanies the code but is not meant for execution. In this way, notebook files serve as a complete computational record of a session including explanatory text and mathematics, code and resulting figures. 

module load python/2.7-ve2
ipython notebook --pylab inline

Download (try this at home)

A basic system for scientific computing consists of Python, ipython, numpy/scipy, pylab, and an editor of your choice

The python(x,y) distribution contains all that above.
