FTP protocol is a protocol used for file transfer (programming)

FTP (File Transfer Protocol) is a standard protocol for file transfer over a computer network. It allows file upload and download operations between the client and the server. The FTP protocol is based on a client-server architecture, where the client communicates with the server by establishing a connection and uses a series of commands to send and receive files.

In programming, we can use various programming languages ​​to implement the functions of the FTP protocol. Below is an example using the Python programming language that demonstrates how to use the ftplib library for FTP file transfer:

import ftplib

# 连接FTP服务器
ftp = ftplib.FTP("ftp.example.com")
ftp.login("username", "password")

# 列出服务器上的文件列表
file_list =
