How to move a file?

I looked into the Python os interface, but was unable to locate a method to move a file. How would I do the equivalent of $ mv ... in Python?

>>> source_files = '/PATH/TO/FOLDER/*'
>>> destination_folder = 'PATH/TO/FOLDER'
>>> # equivalent of $ mv source_files destination_folder

os.rename(), shutil.move(), or os.replace()

All employ the same syntax:

import os
import shutil

os.rename("path/to/current/file.foo", "path/to/new/destination/for/file.foo")
shutil.move("path/to/current/file.foo", "path/to/new/destination/for/file.foo")
os.replace("path/to/current/file.foo", "path/to/new/destination/for/file.foo")

Note that you must include the file name (file.foo) in both the source and destination arguments. If it is changed, the file will be renamed as well as moved.

Note also that in the first two cases the directory in which the new file is being created must already exist. On Windows, a file with that name must not exist or an exception will be raised, but os.replace() will silently replace a file even in that occurrence.

As has been noted in comments on other answers, shutil.move simply calls os.rename in most cases. However, if the destination is on a different disk than the source, it will instead copy and then delete the source file.
