Hi:
An initial cut at a python interface to netCDF 4 is available at 
http://www.cdc.noaa.gov/people/jeffrey.s.whitaker/python/netCDF4.html.
It's got an object oriented API modelled after Konrad Hinsen's netcdf 3 
module (included in his ScientificPython package), but it supports some 
(but not all) netCDF 4 features like groups, multiple unlimited 
dimensions, zlib compression and the new primitive data types.  It does 
not yet support user defined data types (compound, opaque, enum and vlen).
