Clipping multiple feature classes from one input feature.

[AndrewSmith]

I am trying to get this code to work.

What is does is the user assigns a shape or feature class to clip sever pre-defined layers, and rename those layers according to the listed layers.  Such as clip the layers from area of Interest (AOI) and rename them in the new geodatabase as per the original name in the list. 

I keep getting an error such as: 

ARCPY ERRORS:
ERROR 000210: Cannot create output \\Workspace\\scripts\P_2020\Data\P_Data\P_Data\bctsdata
Failed to execute (Clip).

PYTHON ERRORS:
Traceback Info:

Error Info:

Here is my code. Thank you in advance:

Hi Andrew,

I'd suggest adding the '.gdb' extension to your variable denoting the file geodatabase you create a few lines later.

WorkGDB = "MTAP_Data.gdb"

I'm only saying this because the doc relating to CreateFileGDB mentions this file extension in the examples.

Also, you point to a new variable 

outWS = tempdata

outWS, which is a path concatenation of the folder and file gdb.

There seems to be a double up/clash here where the paths to the fileGDB are joined (outWS is already a path to the workGDB so maybe remove the second param 'workGDB' below?

clipfc = os.path.join(outWS,WorkGDB, os.path.basename(fc.split('.')[0]))

It's really helpful to run each tool you use to build your script in arcPro on some data and copy the python snippet from the result, pasting it into your IDE. That way you see what syntax arcpy 'likes' and then structure your params similarly.

Good luck.
