src_file = 'C:\\A\\0.png'

dst_file = 'D:\\B\\1.png'

shutil.copyfile(src_file,dst_file)

def copy(src,dst):

    """copy data and mode bits ("cp src dst")

    The destination may be a directory.

    """

    if os.path.isdir(dst):

        dst = os.path.join(dst,os.path.basename(src))

        copyfile(src,dst)

        copymode(src,dst)
