epoll.register(fd[, eventmask]) Register a fd descriptor with the epoll object.

asyncio.set_event_loop(loop) Equivalent to calling get_event_loop_policy().set_event_loop(loop).

kevent.udata User defined value.

DatagramTransport.sendto(data, addr=None) Send the data bytes to the remote peer given by addr (a transport-dependent target address). If addr is None, the data is sent to the target address given on transport creation. This method does not block; it buffers the data and arranges for it to be sent out asynchronously.

add_flag(flag) Set the flag(s) specified by flag without changing other flags. To add more than one flag at a time, flag may be a string of more than one character.

class os.DirEntry Object yielded by scandir() to expose the file path and other file attributes of a directory entry. scandir() will provide as much of this information as possible without making additional system calls. When a stat() or lstat() system call is made, the DirEntry object will cache the result. DirEntry instances are not intended to be stored in long-lived data structures; if you know the file metadata has changed or if a long time has elapsed since calling scandir(), call os.s

date.toordinal() Return the proleptic Gregorian ordinal of the date, where January 1 of year 1 has ordinal 1. For any date object d, date.fromordinal(d.toordinal()) == d.

importlib.machinery.OPTIMIZED_BYTECODE_SUFFIXES A list of strings representing the file suffixes for optimized bytecode modules. New in version 3.3. Deprecated since version 3.5: Use BYTECODE_SUFFIXES instead.
