datetime.date.fromordinal()

classmethod date.fromordinal(ordinal) Return the date corresponding to the proleptic Gregorian ordinal, where January 1 of year 1 has ordinal 1. ValueError is raised unless 1 <= ordinal <= date.max.toordinal(). For any date d, date.fromordinal(d.toordinal()) == d.

ipaddress.IPv4Address.is_link_local

is_link_local True if the address is reserved for link-local usage. See RFC 3927.

concurrent.futures.Future.running()

running() Return True if the call is currently being executed and cannot be cancelled.

asyncio.IncompleteReadError.partial

partial Read bytes string before the end of stream was reached (bytes).

heapq.heappushpop()

heapq.heappushpop(heap, item) Push item on the heap, then pop and return the smallest item from the heap. The combined action runs more efficiently than heappush() followed by a separate call to heappop().

chunk.Chunk.seek()

seek(pos, whence=0) Set the chunk’s current position. The whence argument is optional and defaults to 0 (absolute file positioning); other values are 1 (seek relative to the current position) and 2 (seek relative to the file’s end). There is no return value. If the underlying file does not allow seek, only forward seeks are allowed.

asyncore.dispatcher.bind()

bind(address) Bind the socket to address. The socket must not already be bound. (The format of address depends on the address family — refer to the socket documentation for more information.) To mark the socket as re-usable (setting the SO_REUSEADDR option), call the dispatcher object’s set_reuse_addr() method.

operator.__iadd__()

operator.__iadd__(a, b) a = iadd(a, b) is equivalent to a += b.

importlib.abc.FileLoader.load_module()

load_module(fullname) Calls super’s load_module(). Deprecated since version 3.4: Use Loader.exec_module() instead.

difflib.SequenceMatcher.get_grouped_opcodes()

get_grouped_opcodes(n=3) Return a generator of groups with up to n lines of context. Starting with the groups returned by get_opcodes(), this method splits out smaller change clusters and eliminates intervening ranges which have no changes. The groups are returned in the same format as get_opcodes().
