merge or append features classes based on a part of their names

PaoloPensalfini

Hi everybody!
I've got ONE file geodatabase with about 400 feature classes (FC). Here attached is a part of that .gdb.
I need to merge that features (or better append one feature - 00 - to the other)  that has got the same name except for the "00".
For example:
"_01P11_line" must be merged with "_01P11_line00"
or better
"_01P11_line00" (input) appended to "_01P11_line" (target)
and, after the merging/appending, delete the "00" feature class.
I'm really a newbie with python...could you help me, please?
Thanks in advance
Paolo

Hello Paolo,

I think the issue is caused because your target feature exists (example "_01P11_line"), but the input does not exist (example "_01P11_line00").

If you modify the script, it will can skip the feature classes that don't have a corresponding "00" feature class:

import arcpy  gdbPath=r"C:\Users\Path\To\Data.gdb"  arcpy.env.workspace = gdbPath  fcList=arcpy.ListFeatureClasses()  for fc in fcList:     if fc.endswith("A"):         tgtFC=fc         inFC=fc+"00" #this line requires there always to be a identical FC ending in '00'         if not arcpy.Exists(inFC):             print inFC+" not found. "+fc+" was skipped."             arcpy.AddMessage(inFC+" not found. "+fc+" was skipped.")             continue         arcpy.Append_management(inFC,tgtFC) #append FC '00' to the FC without '00'. inFC and tgtFC must have the same schema         arcpy.Delete_management(inFC)

As before, you can replace if fc.endswith("line"): with if not fc.endswith("00"):, and then the script will work on points, polygons, lines and annotations at the same time (without the need to duplicate the script).

Let me know if it works or if you run into any other problems.
Good luck!
