Help with arcpy.ListDatasets

[Emilbrundage]

I am simply trying to create a list of all the features within a geodatabase. It seems easy enough, but here is what happens with my script:

>>> import arcpy
>>> from arcpy import env
>>> arcpy.env.workspace = "C:\E1B8\Grid_Create_Update_11-2013\CalcMiles.gdb"
>>> datasetList = arcpy.ListDatasets("*", "Feature")
>>> len(datasetList)
0

My geodatabase contains various features, but as you can see my code creates an empty list. What am I missing?

Thanks!

Are you looking for ListFeatureClasses?

Hi Emil,

The arcpy.ListDatasets function will list the feature datasets in your geodatabase.  If you are looking to create a list of all the feature classes in your geodatabase, try the following:

arcpy.env.workspace = "C:\E1B8\Grid_Create_Update_11-2013\CalcMiles.gdb"

fcList = []

#list feature classes in feature datasets
for dataset in arcpy.ListDatasets("*"):
   for fc in arcpy.ListFeatureClasses("*", "", dataset):
      fcList.append(fc)

#list stand alone feature classes
for fc in arcpy.ListFeatureClasses("*"):
   fcList.append(fc)

print fcList

Ah, I knew it would be something obvious. Thanks for the help guys!

... and if you're wondering why you are not getting any results, then it's because your workspace is not being set correctly:

arcpy.env.workspace = "C:\E1B8\Grid_Create_Update_11-2013\CalcMiles.gdb"

should be:

arcpy.env.workspace = r"C:\E1B8\Grid_Create_Update_11-2013\CalcMiles.gdb"

or

arcpy.env.workspace = "C:/E1B8/Grid_Create_Update_11-2013/CalcMiles.gdb"

Kind regards,

Xander
