ListFeatureClasses returns '[ ]'

Hi,

I'm not able to get the ListFeatureClasses working!

This is a pretty basic code, and I've seen many examples, including in the ESRI 10.1 Help

Note that 'Exists' works!
But not ListFeatureClasses, ListDatasets, ListFiles... - these return '[ ]'

Files are on my C drive (local Hard drive)

Thanks,

Steve

import arcpy
from arcpy import env

env.workspace = "C:/drainagescripting/inputdata/drainagedatasp.gdb"

# THIS WORKS - prints 'true'
print arcpy.Exists("C:/drainagescripting/inputdata/drainagedatasp.gdb")

# THESE return '[ ]'
fclist = arcpy.ListFeatureClasses()
print fclist

If the feature classes reside in feature dataset then you need to include the feature dataset name in the path.

I'm not sure why it wouldn't work for you, assuming there is actually some feature classes in the .gdb.

I modified you code slightly

import arcpy  
from arcpy import env  

env.workspace = theWorkspace = "C:/__temp/test.gdb"  

# THIS WORKS - prints 'true'  
print arcpy.Exists(theWorkspace)  

# THESE return '[ ]'  
fclist = arcpy.ListFeatureClasses()  
print (fclist)‍‍‍‍‍‍‍‍‍‍‍

and my results were..

True
[u'newpts', u'newPtsMySR', u'test', u'testout2', u'StudyZones', u'bl00_point']

so, take a look at your .gdb to see what is in there.
