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)

```
