The modules described in this chapter provide mechanisms for different processes to communicate.
Some modules only work for two processes that are on the same machine, e.g. signal and subprocess. Other modules support networking protocols that two or more processes can used to communicate across machines.
The list of modules described in this chapter is:
|socket||Low-level networking interface.|
|signal||Set handlers for asynchronous events.|
|popen2||Subprocesses with accessible standard I/O streams.|
|asyncore||A base class for developing asynchronous socket handling services.|
|asynchat||Support for asynchronous command/response protocols.|
