Which makes use of the integrated socket type equipment. We name our functionality from the standard Python __main__ block. in the course of runtime, Python assigns values to a couple inner variables reminiscent of __name__. subsequently, __name__ refers back to the identify of the calling procedure. while operating this script from the command line, as proven within the following command, the identify can be __main__, however it can be various if the module is imported from one other script. which means while the module is termed from the command line,.
Socket. during this technique, an example of SupervisorTransport is created with the Unix socket course. Then, an XML-RPC server proxy is created through instantiating the ServerProxy() category of xmlrpclib by way of passing the server handle and formerly created shipping. The XML-RPC server proxy then calls the Supervisor's getAllProcessInfo() procedure, which prints the method info of the kid method. This strategy contains pid, statename, description, etc. 172 Chapter eight Writing a multithreaded.
