• André Gosselin of the Institut Maurice-Lamontagne, Péches & Océans Canada, has implemented pycdf, a new Python interface to the netCDF library. pycdf requires NumPy, the Numeric python package, and installs through the simple "python setyp.py install" command.
• Bill Noon (Cornell) has implemented another netCDF Python module that allows easy creation, access, and browsing of netCDF data. The bindings also use the udunits library to do unit conversions.
• Konrad Hinsen has developed a netCDF interface and integrated it into his ScientificPython package.
• Jeff Whitaker of the NOAA Earth System Research Lab has developed a netCDF-4 module for python.
• Dave Brown of NCAR's Computational and Information Systems Laboratory has developed PyNIO, a Python package that allows read and/or write access to a variety of data formats using an interface modeled on netCDF. Currently supported formats include netCDF, HDF4, GRIB1 (read only), and HDF-EOS Grid and Swath data (read only).
• Christian Dieterich of the University of Chicago wrote pynci, which provides access to the C netCDF interface from the Python prompt.

Annotated examples of complete Python netCDF programs (using the ScientificPython package) are available from the program examples page.

NetCDF-4 note:  Jeff Whitaker's python module handles classic-model netCDF-4 files, multiple unlimited dimensions, groups, compression, and new netCDF-4 atomic types, but not user-defined types.
