I am Having Issues with ERROR 000732

WinnMcEnery3

I am attempting to run a nested for loop to clip habitat types by Marine Protected Area (MPA) region offshore California.   When running the code below I receive error 000732 (red text).  Any help is greatly appreciated.

  File "C:\Python27\ArcGIS10.3\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 326, in RunScript

    exec codeObject in __main__.__dict__

  File "E:\BlueCarbon\GIS\Script\MPARegionClip.py", line 19, in <module>

    arcpy.Clip_analysis(fc, reg, op_FC)

  File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\analysis.py", line 56, in Clip

    raise e

ExecuteError: Failed to execute. Parameters are not valid.

ERROR 000732: Clip Features: Dataset CentralCoastProj.shp does not exist or is not supported

Failed to execute (Clip).

CODE:

import arcpy

from arcpy import env

#Set Variables

hab_Workspace = "E:\\BlueCarbon\\GIS\\Workspace\\habproj "

regWorkspace = "E:\\BlueCarbon\\GIS\\Workspace\\IndRegProj\\"

tWorkspace = "E:\\BlueCarbon\\GIS\\Workspace\\habproj_regions"

env.workspace = regWorkspace

region = arcpy.ListFeatureClasses("")

env.workspace = hab_Workspace

FClist = arcpy.ListFeatureClasses("")

print FClist

for fc in FClist:

    for reg in region:

        op_FC = tWorkspace + "\\" + fc + reg

        arcpy.Clip_analysis(fc, reg, op_FC)

You're running into issues because you can only have one workspace environment at a time. You set the workspace to the region folder. The region list is populated with the names (not full paths) of the feature classes in the region workspace folder. Then, you switch the workspace to the hab workspace folder. The FClist is populated with feature class names (not full paths) of the feature classes in the hab workspace folder. Your loops cycle through the feature class names (not full paths) in your lists. Finally, your clip tool is run against two feature class names (not full paths). Since the tool is provided with feature class names (not full paths) it looks for feature classes in the workspace environment folder - your hab folder.

The most direct route I see to a solution is to store the full path in your lists, some thing like:

>>> import os
... arcpy.env.workspace = r'C:\junk'
... region = [os.path.join(arcpy.env.workspace,fc) for fc in arcpy.ListFeatureClasses("")]
