AttributeError: 'module' object has no attribute 'da'

Hello

I try to edit attribute table for 20 shapefiles that spread in big a folder and are divided to a lot of sub folders. All shapefiles are called "migrashim" and the name of the filed that i want to change is "structuretype". I try this code:

when i run this code:

import arcpy,os,sys
from arcgisscripting import da


pattern = 'migrashim.shp'
folder = r"C:\Project\layers" ## root folder
field = 'YEUD' ## your field where calculation to be applied
files_process = []
for root,dirs,files in os.walk(r"C:\Project\layers"):
    for filenames in files:
        if filenames == pattern:
            files_process.append(os.path.join(root, filenames))


for i in files_process:
    curU = arcpy.UpdateCursor(i)
    for row in curU:
        row.setValue(field, 500)##Any expression you want
        curU.updateRow(row)
del curU

i get an error:

try to see if you get a list of the properties...

why do you need to use arcgisscripting.da when arcpy.da is normally used?

>>> import arcpy
>>> import arcgisscripting
>>>
>>> a = dir(arcpy.da)
>>> b = dir(arcgisscripting.da)
>>>
>>> a
['Domain', 'Editor', 'ExtendTable', 'FeatureClassToNumPyArray', 'InsertCursor', 'ListDomains', 'ListFieldConflictFilters', 'ListReplicas', 'ListSubtypes', 'ListVersions', 'NumPyArrayToFeatureClass', 'NumPyArrayToTable', 'Replica', 'SearchCursor', 'TableToNumPyArray', 'UpdateCursor', 'Version', 'Walk', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__']
>>> b
['Domain', 'Editor', 'ExtendTable', 'FeatureClassToNumPyArray', 'InsertCursor', 'ListDomains', 'ListFieldConflictFilters', 'ListReplicas', 'ListSubtypes', 'ListVersions', 'NumPyArrayToFeatureClass', 'NumPyArrayToTable', 'Replica', 'SearchCursor', 'TableToNumPyArray', 'UpdateCursor', 'Version', 'Walk', '__doc__', '__name__', '__package__']

Well that means that you can't even import arcpy which means one of several things

ArcGIS isn't installed on that machine
or it isn't installed properly
or you have installed it in a non-default location
you are using a different version of python than the one that comes with arcgis

my python worked fine till i run this code (fuond it in the net):

import arcpy,os,sys pattern = 'fish_46.shp' folder = 'C:\Users\USER_NAME\Desktop\delete'## root folder field = 'Id' ## your field where calculation to be applied files_process = [] for root,dirs,files in os.walk('C:\Users\USER_NAME\Desktop\delete'): for filenames in files: if filenames == pattern: files_process.append(os.path.join(root, filenames)) for i in files_process: curU = arcpy.da.UpdateCursor(i,field) for row in curU: row[0]=1 ##Any expression you want curU.updateRow(row) del curU

what can i do?

Ahh if the Mom won't help we will try Dad...but in short I will not get into parental disputes and let your figure it out in the parental forum

interesting though... you have a bigger issue...

>>> import arcpy
>>> import os
>>> rootPath = r"c:\!np_arc"
>>> pattern = "AOI_mtm9.shp"
>>> files_process = []
>>> for root, dirs, files in os.walk(rootPath):
...  for filename in files:
...  if filename == pattern:
...    files_process.append(os.path.join(root, filename))
...
>>> files_process
['c:\\!np_arc\\Basics\\np05\\Shapefiles\\AOI_mtm9.shp', 'c:\\!np_arc\\mapping\\shapefiles\\AOI_mtm9.shp', 'c:\\!np_arc\\Shapefiles\\AOI_mtm9.shp']
>>> for i in files_process:
...  curU = arcpy.SearchCursor(i)
...  for row in curU:
...    print "do nothing"
...
do nothing
do nothing
do nothing
>>>
