The code I have now:
import os
Tree = {}
Tree = os.listdir('Dir')
>>> print(Tree)
['New Folder', 'Textfile1.txt', 'Textfile2.txt']
That doesn't print out the files in the subdirectories. (New Folder is a subdirectory).
My question is, how can I output all the files in the directory and the files in subdirectories?
import os
def Test1(rootDir):
list_dirs = os.walk(rootDir)
for root, dirs, files in list_dirs:
for d in dirs:
print os.path.join(root, d)
for f in files:
print os.path.join(root, f)
OR:
import os
def Test2(rootDir):
for lists in os.listdir(rootDir):
path = os.path.join(rootDir, lists)
print path
if os.path.isdir(path):
Test2(path)
For the test file tree:
E:\TEST
│--A
│ │--A-A
│ │ │--A-A-A.txt
│ │--A-B.txt
│ │--A-C
│ │ │--A-B-A.txt
│ │--A-D.txt
│--B.txt
│--C
│ │--C-A.txt
│ │--C-B.txt
│--D.txt
│--E
Running the following code:
Test1('E:\TEST')
print '======================================='
Test2('E:\TEST')
You can see there are difference between the results:
>>>
E:\TEST\A
E:\TEST\C
E:\TEST\E
E:\TEST\B.txt
E:\TEST\D.txt
E:\TEST\A\A-A
E:\TEST\A\A-C
E:\TEST\A\A-B.txt
E:\TEST\A\A-D.txt
E:\TEST\A\A-A\A-A-A.txt
E:\TEST\A\A-C\A-B-A.txt
E:\TEST\C\C-A.txt
E:\TEST\C\C-B.txt
=======================================
E:\TEST\A
E:\TEST\A\A-A
E:\TEST\A\A-A\A-A-A.txt
E:\TEST\A\A-B.txt
E:\TEST\A\A-C
E:\TEST\A\A-C\A-B-A.txt
E:\TEST\A\A-D.txt
E:\TEST\B.txt
E:\TEST\C
E:\TEST\C\C-A.txt
E:\TEST\C\C-B.txt
E:\TEST\D.txt
E:\TEST\E
>>>
To save them in a list:
import os
files = []
def Test1(rootDir):
files.append(rootDir)
list_dirs = os.walk(rootDir)
for root, dirs, files in list_dirs:
for d in dirs:
files.append(os.path.join(root, d))
for f in files:
files.append(os.path.join(root, f))
import os
files = [rootDir]
def Test2(rootDir):
for lists in os.listdir(rootDir):
path = os.path.join(rootDir, lists)
files.append(path)
if os.path.isdir(path):
Test2(path)
From recipe 577091 on the Python Cookbook, you might use or learn from the TREE Emulator there.
