A new file is stored in one location. Write a code snippet that moves it to a different target location.

In Python you can move a file using the shutil module. The move operation is atomic on most file systems and preserves metadata. Example:

import shutil
source = "/path/to/source/file.txt"
target = "/path/to/target/file.txt"
shutil.move(source, target)

If you need to handle errors, wrap in a try/except block. Complexity is O(1) for the move call, but the underlying copy may be O(n) in bytes if the file system does not support atomic moves across different devices. This snippet works on Windows, macOS, and Linux.
