ftp上传完后怎么

import ftplib

# Example usage
ftp_host = 'example.com'
ftp_user = 'user'
ftp_pass = 'password'
local_file = 'local.txt'
remote_file = 'remote.txt'

upload_file(ftp_host, ftp_user, ftp_pass, local_file, remote_file)
verify_file_integrity(local_file, remote_file, ftp_host, ftp_user, ftp_pass)
