Can't reproduce this here

>>> from netCDF4 import Dataset
>>> f = Dataset('nws_precip_conus_20120810.nc')

>>> print f
<type 'netCDF4.Dataset'>
root group (NETCDF3_CLASSIC file format):
    dimensions: hrapy, hrapx, latlong, dates
    variables: amountofprecip, lat, lon, true_lat, true_lon, timeofdata, timeofcreation, hrap_xor, hrap_yor
    groups: 

I got the file from http://water.weather.gov/precip/p_download_new/2012/08/10/.

Christoph - would you mind trying this with the py27 windows version?

I wonder if it has to do with the way windows paths are handled - what if you 
try it in the directory that the file is in (so you can simply do nc = 
NetCDFFile('nws_precip_conus_20120810.nc'))?

There's a newline character, '\n', in 
'C:\Python27\nws_precip_conus_20120810.nc'. Try 
r'C:\Python27\nws_precip_conus_20120810.nc' or 
'C:/Python27/nws_precip_conus_20120810.nc'. Works for me.
