search in folders and .gdb and rename featureclass part 2

PeterVersteeg

Hi,

At the end off part 1 i am able to search folders and Gdb's for featureclasses. for the next part i want to rename a feature in the "feature_class" list.so far i have this:

import os  
import arcpy  


workspace = "D:\GIS\Zone1\Zone1A"
datatypes = "FeatureClass"
arcpy.env.overwriteOutput = True


def inventory_data(workspace, datatypes):  
    for path, path_names, data_names in arcpy.da.Walk(  
            workspace, datatype=datatypes, type="Polygon"):
        for data_name in data_names:  
            yield os.path.join(path, data_name)  
  
for feature_class in inventory_data(workspace, "FeatureClass"):
    print feature_class
    if feature_class == "RenameTest":
        arcpy.Rename_management("RenameTes2", "RenameTest2")
print feature_class

can sameone point to me were i am going wrong.

thank you and greetings Peter

It is not necessary to create a double loop, but to provide a sample that does not have that much changed see the script below.

• I introduced a dictionary "dct" holding the input name and the output name as key, value pair
• in the second loop the fc is split into the workspace and the featureclass name
• if the old name is in the dictionary (in the keys) then it is renamed

import arcpy
import os

workspace = "D:\GIS\ZOne1\Zone1A"
feature_classes = []
walk = arcpy.da.Walk(workspace, datatype="FeatureClass", type="Polygon")

dct = {'featureclassName': 'featureclassName_renameTest',
      'featureclassName1': 'featureclassName1_renameTest',
      'another input name': 'corresponding output name'}

for dirpath, dirnames, filenames in walk:
    for filename in filenames:
        feature_classes.append(os.path.join(dirpath, filename))

for fc in feature_classes:
    fc_ws, fc_name = os.path.split(fc)
    if fc_name in dct:
        arcpy.Rename_management(fc, os.path.join(fc_ws, dct[fc_name]))
