Looking forward to finding a solution! import socket import sys from _thread import * host = '' port = 5555 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) try: s.bind((host, port)) except socket.error as e: print(str(e)) s.listen(5) def threaded_client(conn): conn.send(str.encode('Welcome, type your info \n')) while True: data = conn.recv(2048) reply = 'Server output: '+data.decode('utf-8') if not data: break conn.sendall(str.encode(reply)) conn.close() while True: conn, addr = s.accept() print('connected to:

i got a challenge to create: messaging system comprised of 2 components - client and server. 3 types of messaging: 1) respond with current server time 2) respond with number of calls made to the server so far(*since it started running) 3) multiplication of two numbers. i have tried to do that with python, so i saw this video tutorial : [this video] and read this guide: [LINK] but i have a big lack understanding, how the server knows what the client asking for? and how the server can respond for each query, what can i see its only the bytes receive.. i hope that someone can help me i have only 24 hours to answer that (it's a challenge for work) note: im a new computer science student. thank you al
