get the data type of a field in specific

ElenaG — Fri, 12 Apr 2013 17:06:32 GMT

Hello

I need to get the data type of a specific field, example field "NAME", not all fields of the Feature Class as does ListFields or Describe.

Thanks:confused:

Just search for that field while looping through the feature classes and then perform a describe on that searched field.

not in time to get the field that I seek

import arcpy
... arcpy.env.workspace = "C:\GISProgramming101\Exercises\Data"
... infc= "Streets.shp"
... fieln="FULL_STREE"
... desc= arcpy.Describe(infc)
... fields = desc.fields
... for field in fields:
... if field ==fieln:
... print "type: " % field.type

Look at the features properties in ArcCatalog

It will fully tell you the type of field and various parameters for it. Such as length of a string field or long or short integer or double precision etc...

ListFields takes a wildcard for the field name, passing in the field name should only return the single field.

import arcpy
arcpy.env.workspace = "C:\GeoSpatialTraining\GISProgramming101\Exercises\Data"
infc= "Streets.shp"
fieln="FULL_STREE"
field = arcpy.ListFields(infc,fieldn)[0]
print field.type
