局域網傳輸文件是最最常用的功能，我參考https://www.jb51.net/python/345837qrz.htm這篇文章，復制粘貼，開發了一個。但發現進度條沒有用，也沒有顯示傳輸用時和傳輸速度的功能，于是我改寫了代碼，使它實現這個功能。
import socket
import osdef start_server(host='192.168.1.145', port=8888):server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server_socket.bind((host, port))server_socket.listen(1)print(f"服務器啟動，監聽 {host}:{port}")while True:client_socket, addr = server_socket.accept()print(f"連接來自 {addr}")# 接收文件名和大小file_info = client_socket.recv(1024).decode()file_name, file_size = file_info.split('|')file_size = int(file_size)# 創建文件并寫入數據with open('d:/socketfile/'+file_name, 'wb') as file:received = 0while received < file_size:data = client_socket.recv(4096)file.write(data)received += len(data)print(f"接收進度: {received}/{file_size} 字節")client_socket.close()print(f"文件 {file_name} 接收完成")if __name__ == "__main__":start_server()上面是服務器端，沒有怎么改，增加了'd:/socketfile/'+file_name，把文件放在我們想要放的文件夾。

以上就改動比較大，也讓我慢慢熟悉面向對象編程，用self.可以為公用變量，增加時間和速度的顯示，原來代碼出現tk.Progressbar報錯，進度條無法正常顯示等問題。
速度還是可以的。
用一段時間，感覺還是不爽，要開2個程序，一個是服務器端，一個是客戶端，才能在2臺電腦中互傳文件，為此，我把它一體化，只要用一個程序就實現了服務器端和客戶端的功能，又能接受文件，又能發送文件。同時，加上我一直喜歡用的拖放功能，不能每次去選擇文件傳輸。

填好ip，點擊啟動服務器就可以接收文件。下面還能顯示接收到的文件。
