Ways to Move up and Down the dir structure in Python

Question

#Moving up/down dir structure
print os.listdir('.')
print os.listdir('..')
print os.listdir('../..')

Any othe ways??? I got saving dirs before going deeper, then reassigning later.

Answer 1

Of course there are - thre are both os.walk - which returns tuples with the subdirectories, and the files tehrein as os.path.walk, which takes a callback function to be called for each file in a directory structure.

You can check the online help for both functions.

Answer 2

You can use os.chdir()

http://docs.python.org/library/os.html#os-file-dir

Am I missing something in the question?

Answer 3

This should do the trick:

for root, dirs, files in os.walk(os.getcwd()):
    for name in dirs:
        try:
            os.rmdir(os.path.join(root, name))
        except WindowsError:
            print 'Skipping', os.path.join(root, name)

This will walk the file system beginning in the directory the script is run from. It deletes the empty directories at each level.

Answer 4

"and what if you wanted to move all the files up to the root directory?"

You could do something like:

for root, dirs, files in os.walk(os.getcwd()):
    for f in files:
        try:
            shutil.move(os.path.join(root, f), os.getcwd())
        except:
            print f, 'already exists in', os.getcwd()
