How to set workspace from input Feature Class ? is there an attribute of the source GDB for a feature class ? some times the FC is in a dataset and some time it isn't, How can i get the path of source GDB for setting workspace when the input is dynamic ?

Use the catalogPath property of the Describe object.

For example:

dirname = os.path.dirname(arcpy.Describe(feat_class).catalogPath)
desc = arcpy.Describe(dirname)
if hasattr(desc, "datasetType") and desc.datasetType=='FeatureDataset':
    dirname = os.path.dirname(dirname)
  • the catalog path function gives the path with the dataset, for setting workspace i need the path to the GDB only (without the data set) – Geog Aug 31 '14 at 8:25
  • @Geog Luke is correct. os.path.dirname() extracts the workspace out of the full path. – radouxju Aug 31 '14 at 8:53
  • @Geog Use os.path.dirname twice. See edit. – user2856 Aug 31 '14 at 8:58
  • You can also try using the path property of the Describe object: stackoverflow.com/a/36905906/2457991 – Adam Apr 28 '16 at 5:28
