List files inside folders in Arcpy?

Question

I have done the procedure to list shapefiles in an environment but it returns the folder names inside the envirnoment:

arcpy.env.workspace  = r"C:\Users\user\Desktop\results"
dd= arcpy.ListFiles()
for i in dd:
    print(i)

gives:

shapesfiles1  
shapefiles2

How to print what is inside these folders?

Answer 1

arcpy.da.Walk() can do this, documentation

This would list all files found:

import arcpy
import os

arcpy.env.workspace = r"C:\Users\user\Desktop\results"

walk = arcpy.da.Walk(datatype="FeatureClass")

for dir_path, dir_names, file_names in walk:
    for filename in file_names:
        print(filename)

Or if you want the full path:

import arcpy
import os

arcpy.env.workspace = r"C:\Users\user\Desktop\results"

walk = arcpy.da.Walk(datatype="FeatureClass")

for dir_path, dir_names, file_names in walk:
    for filename in file_names:
        print(os.path.join(dir_path, filename))
