search in folders and .gdb and rename featureclass part 2

PeterVersteeg — Sat, 11 Dec 2021 16:29:12 GMT

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

Can you be more specific about what's "going wrong" - what's your problem, do you get any error messages, etc...?

The 2nd example in the Help is quite useful.

I am not sure the function return any list that can be used by the for statement.

Check the examples here: http://resources.arcgis.com/en/help/main/10.2/002z/002z00000011000000.htm

The last few examples are very close to what you need.

Have fun

My first script got me the featureclasses with there path, this is not what i want for my rename. now i got this:

import arcpy
import os


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


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


for fc in filename:
    if fc == "featureclassName":
        arcpy.Rename_management("featureclassName", "featureclassName_renameTest")
    elif fc == "feature

elif fc == "featureclassName1":

arcpy.Rename_management("featureclassName1", "featureclassName1_renameTest")

(sorry samehow i cannot add more line to the script)

the print on line 13 gives me a list of all featureclasses i want to rename. but my rename is not working i do not get a error

greetings Peter

looking at this i think i know what wrong but i do not know how to solve it.

the Rename_management in my script do's not know from what .gdb the feature name i use is from.

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]))

I am trying to learn arcpy (python) and was looking for a project i can use at work. Perhaps this was a bit to much for now but i am analyzing your script and reading about the parts i do not understand yet.

The script works great and i even understand 80% off the code.

Greetings Peter
