Python:select is the select module of the Python standard library, which provides I/O multiplexing: it watches multiple file descriptors or sockets in a single thread and waits until they become ready for reading or writing. Because it is a thin wrapper around the operating system's select(), poll(), epoll, and kqueue calls, the available functions differ by platform. If a high-level interface is needed, the selectors module is recommended.
