Networking and Interprocess Communication

The modules described in this chapter provide mechanisms for networking and inter-processes communication.

Some modules only work for two processes that are on the same machine, e.g. signal and mmap. Other modules support networking protocols that two or more processes can use to communicate across machines.

The list of modules described in this chapter is:

• asyncio --- Asynchronous I/O
• socket --- Low-level networking interface
• ssl --- TLS/SSL wrapper for socket objects
• select --- Waiting for I/O completion
• selectors --- High-level I/O multiplexing
• asyncore --- Asynchronous socket handler
• asynchat --- Asynchronous socket command/response handler
• signal --- Set handlers for asynchronous events
• mmap --- Memory-mapped file support
