如何与 Python 中已经运行的 Linux 进程通信？

Question

I am simulating an https session between a client and server within the same Ubuntu Linux virtual machine. Naturally, the client process ( client.py ) sends requests to the server process ( server.py ) which will already be running before the client spawns to make its request. For security reasons, I would prefer avoid spawning an intermediate shell to pass commands to the server via something like the system() function call [ os.system module ]; The server is an independent process that is already running so it does not make sense to use the subproccess module in Python because the server will not be a child process. Do I have to use sockets? If so, what python module supports sockets? Is there some other form of interprocess communication on Linux? What to do? Thanks

You might have a look at ZeroMQ . It is simple to use and it provides a single abstraction to various communication modes, including sockets.
