List ArcGIS geodatabase feature classes on Python console using ListFeatureClass function

Question

I am trying to create a new script with a hard-coded geodatabase filename, that lists the feature classes it contains to the console. I know there are several ways to do this, but I decided to to use ListFeatureClasses function. I barely started studying Python, so I know very basic stuff, but I would like to get help with this.

I tried the following code, but it does not print anything and does not even give me any error message. I opened up ArcGIS Pro, added the geodatabase to my map, and wrote this code in the built-in Python console. Is there any step I am missing or something wrong with my code?

import arcpy
import os

arcpy.env.workspace = "X:\311\Obtaining GIS Data\TaxParcels.gdb"

datasets = arcpy.ListDatasets(feature_type='feature')
datasets = [''] + datasets if datasets is not None else []

for ds in datasets:
    for fc in arcpy.ListFeatureClasses(feature_dataset=ds):
        path = os.path.join(arcpy.env.workspace, ds, fc)
        print(fc)

Answer 1

If your fGDB actually does have feature datasets (not just top-level feature classes), you could do:

import arcpy
import os

arcpy.env.workspace = r"X:\311\Obtaining GIS Data\TaxParcels.gdb"

#  Get top-level feature classes
featureclasses = arcpy.ListFeatureClasses()

#  Get data-set feature classes
datasets = arcpy.ListDatasets()
for ds in datasets:
    featureclasses.extend(arcpy.ListDatasets(feature_dataset=ds))

for fc in featureclasses:
    print(fc)

Otherwise, if your fGDB does not have feature datasets (or if you're not interested in the feature classes within feature datasets), then it would simply be:

import arcpy
import os

arcpy.env.workspace = r"X:\311\Obtaining GIS Data\TaxParcels.gdb"
featureclasses = arcpy.ListFeatureClasses()

for fc in featureclasses:
    print(fc)

Not sure if this is the root of your problem, but spaces in your file path can lead to unwanted (or no) results in your code. If you can, replace spaces with underscores or, better yet, camelCaseText. Also, it is a good habit to use r in your path so Python reads it as a text string:

arcpy.env.workspace = r"X:\311\Obtaining GIS Data\TaxParcels.gdb"
