将下列代码用进程或线程的方式改写while True: print('等待客户连接...\r\n'); cs,caddr=ss.accept() print('连接来自于：',caddr) data='欢迎你的到来！\r\n' cs.sendall(bytes(data,'utf-8')) data=cs.recv(1024).decode('utf-8') if not data: break print('三角形三边长为:',data) sides=data.split(',') cs.sendall(bytes(''+str(triangle(float(sides[0]), float(sides[1]),float(sides[2]))),'utf-8')) cs.close() ss.close() from socket import * s=socket(AF_INET,SOCK_STREAM,0) s.connect(('127.0.0.1',5005)) data=s.recv(1024).decode('utf-8') if data: print(data) a=input("请输入边长a:") b=input("请输入边长b:") c=input("请输入边长c:") data=a+','+b+','+c if data: s.sendall(bytes(data,'utf-8')) data=s.recv(1024).decode('utf-8') if data: print('三角形面积为：',data) s.close()

使用线程方式改写：

import threading
from socket import *

def handle_client(cs):
    print('连接来自于：', cs.getpeername())
    data = '欢迎你的到来！\r\n'
    cs.sendall(bytes(data, 'utf-8'))
    data = cs.recv(1024).decode('utf-8')
    if not data:
        return
    print('三角形三边长为:', data)
    sides = data.split(',')
    cs.sendall(bytes('' + str(triangle(float(sides[0]), float(sides[1]), float(sides[2]))), 'utf-8'))
    cs.close()

def client_thread():
    s = socket(AF_INET, SOCK_STREAM, 0)
    s.connect(('127.0.0.1', 5005))
    data = s.recv(1024).decode('utf-8')
    if data:
        print(data)
    a = input("请输入边长a:")
    b = input("请输入边长b:")
    c = input("请输入边长c:")
    data = a + ',' + b + ',' + c
    if data:
        s.sendall(bytes(data, 'utf-8'))
    data = s.recv(1024).decode('utf-8')
    if data:
        print('三角形面积为：', data)
    s.close()

ss = socket(AF_INET, SOCK_STREAM, 0)
ss.bind(('127.0.0.1', 5005))
ss.listen(5)

print('等待客户连接...\r\n')

while True:
    cs, caddr = ss.accept()
    thread = threading.Thread(target=handle_client, args=(cs,))
    thread.start()

    client_thread()

使用进程方式改写：

import multiprocessing
from socket import *

def handle_client(cs):
    print('连接来自于：', cs.getpeername())
    data = '欢迎你的到来！\r\n'
    cs.sendall(bytes(data, 'utf-8'))
    data = cs.recv(1024).decode('utf-8')
    if not data:
        return
    print('三角形三边长为:', data)
    sides = data.split(',')
    cs.sendall(bytes('' + str(triangle(float(sides[0]), float(sides[1]), float(sides[2]))), 'utf-8'))
    cs.close()

def client_process():
    s = socket(AF_INET, SOCK_STREAM, 0)
    s.connect(('127.0.0.1', 5005))
    data = s.recv(1024).decode('utf-8')
    if data:
        print(data)
    a = input("请输入边长a:")
    b = input("请输入边长b:")
    c = input("请输入边长c:")
    data = a + ',' + b + ',' + c
    if data:
        s.sendall(bytes(data, 'utf-8'))
    data = s.recv(1024).decode('utf-8')
    if data:
        print('三角形面积为：', data)
    s.close()

ss = socket(AF_INET, SOCK_STREAM, 0)
ss.bind(('127.0.0.1', 5005))
ss.listen(5)

print('等待客户连接...\r\n')

while True:
    cs, caddr = ss.accept()
    process = multiprocessing.Process(target=handle_client, args=(cs,))
    process.start()

    client_process()
