C# 中是否有等效于.isConnected 功能的 python

Question

I have been looking for the equivalent of [isConnected() functionality] of C# in PYTHON. https://docs.microsoft.com/en-us/dotnet/api/system.net.sockets.socket.connected?view=net-5.0

What I basically need is to check if the socket connection is still open on another end (primary server). If not, move the connection to a new socket(backup server).

I have been quite blank as to how I can move the existing connection to another server without having to reconnect again. Any kind of guidance and help will be really appreciated.

Right now, my connection to server is done at Login(). I want that just in case primary disconnects, the existing username moves to secondary. He just should perform file and word operations. What changes should I do in my code to achieve this.

My current code structure is: Client side:

 def file_operation():
      do_something

 def word_addition():
      do_something

 def login():
      s.connect(host,port)

if __name__ == "__main__":

Server side:

  def accept_client():
      s.accept
      do_something

  def GUI():
     accept_client()

if __name__ == "__main__":

According to the Python Sockets documentation , no, there isn't. Python sockets are merely a wrapper around the Berkeley Sockets API, so whatever is in that API, that's what's in the Python API.

If you look at the source code for Microsoft's Socket.cs class , you'll see that they maintain a boolean flag field m_IsConnected to indicate the socket's current connection status. You could potentially do the same with your own custom sockets class, using Microsoft's code as a model for writing your Python code.

Or, you could simply use the socket as you normally would, and switch to a different server when a socket error occurs.
