多进程和多线程

并行的前提是要有多核CPU

#server.py
from multiprocessing import Process
from threading import  Thread
import  socket
server =socket.socket()
server.bind(('0.0.0.0',8006))
server.listen(1000)

def func(connection):
    recv_data=connection.recv(1024)
    if recv_data:
        print(recv_data.decode('utf-8'))
        connection.send(recv_data)
    else:
        connection.close()
    pass

while True:
    #多进程，多进程消耗资源大，python框架都是多线程的
    t = Thread(target=func, args=(connection,))  # 传给func的位置参数args必须是元祖
    t.start()



    # #多线程只需要将Process改成Thread
    # connection,remote_address=server.accept()
    # p=Process(target=func,args=(connection,))  #传给func的位置参数args必须是元祖
    # p.start()




#### client.py
import socket
while True:
    
    client=socket.socket()
    client.connect(('127.0.0.1', 8001))
    msg=input('>>>输入：')
    client.send(msg.encode('utf-8'))
    print(client.recv(1024).decode('utf-8'))
    client.close()
