Have many feature classes in geodatabases and eventually want to run more complex processes on them. Having trouble with the basics - can anyone tell me what I am doing wrong with the following? If I use "print fcscopy" I get the list of output file names I want.. but the featureclass to featureclass gives following error.

#Code
import arcpy

arcpy.env.workspace = r"D:\_StuData\GIS\Projects\PersonalProjects\Product\test.gdb"
fcs = arcpy.ListFeatureClasses() 
copy = 'copy'
fcscopy = [x + copy for x in fcs]
outpath = "D:\\_StuData\\GIS\\Projects\\PersonalProjects\\Product\\test.gdb"

arcpy.FeatureClassToFeatureClass_conversion(fcs, outpath, fcscopy)

Error

Runtime error Traceback (most recent call last): File "", line 12, in File "c:\program files (x86)\arcgis\desktop10.3\arcpy\arcpy\conversion.py", line 1789, in FeatureClassToFeatureClass raise e RuntimeError: Object: Error in executing tool

Testing

>>> print fcs

[u'Border', u'Building', u'Concrete', u'Grass', u'Gravel', u'Rocks', u'Roof']

>>> print fcscopy

[u'Bordercopy', u'Buildingcopy', u'Concretecopy', u'Grasscopy', u'Gravelcopy', u'Rockscopy', u'Roofcopy']

arcpy.ListFeatureClasses() returns a list of the names of the feature classes. However, arcpy.FeatureClassToFeatureClass_conversion requires the path to the feature class. You could incorporate something like this:

import os, arcpy

arcpy.env.workspace = r"D:\_StuData\GIS\Projects\PersonalProjects\Product\test.gdb"

outpath = r"D:\_StuData\GIS\Projects\PersonalProjects\Product\test.gdb"

fcs = arcpy.ListFeatureClasses()

copy = '_copy'

for fc in fcs:
    arcpy.FeatureClassToFeatureClass_conversion(os.path.join(arcpy.env.workspace, fc),outpath, fc+copy)

os.path.join will "join one or more path components intelligently."

    I think because the arcpy.env.workspace has been set the path to the fc isn't required (please correct me if I'm wrong) – Midavalo Jan 19 '16 at 3:38

    I haven't tested it. But that's what I always use. I've had issues in the past with this. Just looked at the documentation, however, and it appears you're right. – Fezter Jan 19 '16 at 3:40

    it won't hurt having the path there I'm sure – Midavalo Jan 19 '16 at 3:41

FeatureClassToFeatureClass requires a single input/output, so you'll need to include within the for loop:

import arcpy
arcpy.env.workspace = r"D:\_StuData\GIS\Projects\PersonalProjects\Product\test.gdb"

fcs = arcpy.ListFeatureClasses()

copy = 'copy'
outpath = r"D:\_StuData\GIS\Projects\PersonalProjects\Product\test.gdb"

for x in fcs:
    arcpy.FeatureClassToFeatureClass_conversion(x, outpath, x + copy)
