A very simple minded solution:

def protect (func, *args):
    if debug:
        print '!!Calling',func.__name__,'with',args
    else:
        apply (func, args)


Then just use:

  protect (shutil.copy, src, dest)

after setting debug.  It would be trivial to add code to ask the user whether
to go ahead and do the command as well.
