Python 服务器无法对整数数组排序并发送到客户端

我试图将随机大小的int数组从多个客户端发送到服务器，服务器将不断地将新接收到的int数组添加到全局数组中，并将累计排序的数组返回给客户端。我的客户端代码能够向服务器发送和接收int数组。但服务器无法读取int数组并进行排序并发送回客户端（我的服务器可以读取原始int数组并发送回客户端，但这不是我想要的）

在我的服务器代码中，注释部分不起作用。我是python和socket编程的新手

Client.py

# Import socket module
import socket, pickle
import random


def Main():
    # local host IP '127.0.0.1'
    host = '127.0.0.1'

    # Define the port on which you want to connect
    port = 12345

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    # connect to server on local computer
    s.connect((host, port))


    while True:

        # Generate Random array to be sent to server
        arr = []
        # Generate random size between 10 and 20
        # random_size = random.randint(10, 20)
        random_size = random.randint(1, 3)

        for i in range(0, random_size):
            arr.append(random.randint(0, 10))
        print('Array = ' + str(arr))

        # Serialise the array to byte stream before sending to server
        data_stream = pickle.dumps(arr)

        #Array byte stream sent to server
        s.send(data_stream)

        # messaga received from server
        data = s.recv(1024)
        #deserialise the byte stream into array after receiving from server
        data_arr = pickle.loads(data)

        # print the received message
        #print('Received', repr(data_arr))
        print('Received from Server: ', data_arr)

        # ask the client whether he wants to continue
        ans = input('\nDo you want to continue(y/n) :')
        if ans == 'y':
            continue
        else:
            break
    # close the connection
    s.close()

我在终端运行它，我看到了错误

NotImplementedError: use ``sl.add(value)`` instead

但这似乎是一个不完整的信息

移除后

bisect.insort(sl, i)

它开始工作了

---

可能有：

使用``sl.add（value）``而不是``bisect.insort（sl，i）`

在终端/控制台/cmd.exe中运行服务器时是否出现错误？不，从pycharm运行服务器时未出现任何错误当我在终端/控制台中运行服务器时，则出现错误

未实现错误：使用``sl.add（value）``相反

>直接在终端中运行，而不是在PyCharm中运行。什么是“不工作”呢？制作一个具有预期与实际输出的可复制示例，并对任何错误消息进行完整回溯。阅读此外，套接字也不是基于消息的

recv（1024）

可以接收0（套接字关闭）或1-1024字节。这些可能是前一次发送的一部分，甚至是两次不同发送的一部分。您所知道的是，您以相同的顺序发送字节。你必须设计一个协议来确保你有一个完整的消息。用一个特殊的字节或序列来分隔消息，首先发送消息的大小，等等@MarkTolonen有了这个想法，但是对于像我这样的小整数数组，我相信它应该可以工作。感谢您提醒Hanks它很有效，我忘了删除我尝试用于普通列表的bisect.insort（）。你知道在带对分的列表中，哪一个更有效吗？我不知道哪一个更有效。我第一次看到两个。您可以使用大量随机数据和检查时间来运行两者。
