i've sorted out writing "variable.dtype" instead of "variable.datatype"

i've got another problem. i can't have access to variable fill values
 which is the correct syntax?

i've tried (see attached code)

varin._Fillvalue

but it doesn't work

thank you so much

It's _FillValue.  Most likely that attribute doesn't exist, and the netCDF 
default fill value was used.  The default values are defined in the include 
file netcdf.h: NC_FILL_CHAR, NC_FILL_BYTE, NC_FILL_SHORT, NC_FILL_INT, 
NC_FILL_FLOAT, and NC_FILL_DOUBLE.  

Please use the github site (https://github.com/Unidata/netcdf4-python) in the 
future - the googlecode site is no longer active.

The default fill values are also accessible directly in python:

>>> import netCDF4
>>> netCDF4.default_fillvals
{'i8': -9223372036854775806, 'f4': 9.969209968386869e+36, 'u8': 
18446744073709551614L, 'i1': -127, 'U1': '\x00', 'S1': '\x00', 'i2': -32767, 
'u1': 255, 'i4': -2147483647, 'u2': 65535, 'f8': 9.969209968386869e+36, 'u4': 
4294967295L}
