OSError: Directory not empty raised, how to fix?

I'm just trying to write a little application that takes a value from a file named 'DATA.DAT' and renames the folder which contains that file with that value.

The .py script runs in another folder and allows the user to define the path. To give you a better idea, the user defined path must be like (on a mac) '/Users/User/Desktop/FOLDER' and 'FOLDER' should contain 'DATA.DAT'.

That's how a little part of the source code looks like:

try:
    data = open('DATA.DAT').read()

    data_data = data[12:17]
    path_paths = path.rsplit('/')
    basepath = '/'.join(path_paths[:-1])
    chdir(basepath)

    if path_paths[-1] <> data_data:
        rename(path_paths[-1], data_data)
        raw_input('Folder name has been corrected! Thank you.')
        quit()
    else:
        print('Folder name was already correct! Thank you.')
        quit()
except IndexError:
    raw_input('ERROR!')
    quit()

Well, it works; but it raise and exception when 'FOLDER' contains more than one file (actually, 'FOLDER' should contain just 'DATA.DAT' and other folders. That doesn't give problems.)...

Traceback (most recent call last):
  File "/Users/User/Desktop/example.py", line 72, in <module>
    rename(path_paths[-1], d开发者_运维知识库ata_data)
OSError: [Errno 66] Directory not empty

Just to prevent that this happens, is there a way to fix it? Thanks.

Edit: The right tool is shutil.move:

shutil.move(path_paths[-1], data_data)

assuming path_paths[-1] is the absolute directory you want to rename, and data_data is the absolute directory name you want to rename it to.

The destination directory must not already exist for this to work. The two locations don't need to be on the same filesystem.

Old answer: Use os.renames instead of os.rename.

It will recursively create any needed directories.

It is much easier to use shutil.

Althoug a decade later.. is possible to replace the way for split path

path_paths = path.rsplit('/')

for

path_paths = os.path.split(path)[1]

And for renaming problem:

os.rename('myfolder/oldname', 'myfolder/newname')
