I am looking to find all fields that have all NULLs in a mxd and turn them off

[DanMacDonald]

I this is the code I have tried so far

for lyr in arcpy.mapping.ListLayers(mxd):

...     fields = arcpy.ListFields(lyr)

...     for field in fields:

...         rows = arcpy.SearchCursor(lyr,"","","","")

...         for row in rows:

...             for field in fields.keys():

...                 fields[field].append(row.getValue(field))

I am a newbie trying to get this to run any and all help would be appreciated

Thanks

Is there an error, or what is the problem? What version of ArcGIS are you on?

Is there a need for this from an analysis perspective? Or is this just a preference on presentation?

If is the first, there are ways to handle nulls in data processing and analysis.
