Here's a first draft of a Python 3 script that worked for me. It's much faster than calling cwd(). Pass in server, port, directory, username, and password as arguments. I left output as a list as an exercise for the reader.

        if item[1]['type'] == 'dir':
            dirs.append(item[0])
        else:
            nondirs.append(item[0])
    if nondirs:
        print()
        print('{}:'.format(dir))
        print('\n'.join(sorted(nondirs)))
    else:
        # print(dir, 'is empty')
        pass
    for subdir in sorted(dirs):
        ftp_walk(ftp, '{}/{}'.format(dir, subdir))

ftp = ftplib.FTP()
ftp.connect(sys.argv[1], int(sys.argv[2]))
ftp.login(sys.argv[4], sys.argv[5])
ftp_walk(ftp, sys.argv[3])
