在python ftp上隐藏文件

Question

我有一个使用pyftpdlib的ftp服务器。如何隐藏运行服务器的python文件？你知道吗

这是我的密码：

import os
from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer

def main():
    authorizer = DummyAuthorizer()
    authorizer.add_user('user', '12345', os.getcwd(), perm='elradfmwM')
    handler = FTPHandler
    handler.authorizer = authorizer
    handler.banner = "ftp works."
    address = ('0.0.0.0', 2121)
    server = FTPServer(address, handler)
    server.max_cons = 256
    server.max_cons_per_ip = 5
    server.serve_forever()

if __name__ == '__main__':
    main()
