How to copy files only if the source is newer than the destination in Python?

Question

I\'m writing a script to copy compiled files from one location to another.

What I have at the moment is something like this:

import os
import shutil

You could make use of the file modification time, if that's enough for you:

# If more than 1 second difference
if os.stat(src).st_mtime - os.stat(dest).st_mtime > 1:
    shutil.copy2 (src, dst)

Or call a synchronization tool like rsync.
