Sometimes, we want to get a directory-tree listing in Python.
In this article, we’ll look at how to get a directory-tree listing in Python.
How to get a directory-tree listing in Python?
To get a directory-tree listing in Python, we can use the os.walk method.
For instance, we write
import os
for dirname, dirnames, filenames in os.walk('.'):
for subdirname in dirnames:
print(os.path.join(dirname, subdirname))
for filename in filenames:
print(os.path.join(dirname, filename))
to call os.walk with '.' to return an iterator with the directories and files in the folder.
It traverses the whole directory tree and returns items from all levels.
In the loop, we print out all the child directories with
for subdirname in dirnames:
print(os.path.join(dirname, subdirname))
And we print out all the child file paths with
for filename in filenames:
print(os.path.join(dirname, filename))
