class asyncio.LifoQueue A subclass of Queue that retrieves most recently added entries first.

ipaddress.v4_int_to_packed(address) Represent an address as 4 packed bytes in network (big-endian) order. address is an integer representation of an IPv4 IP address. A ValueError is raised if the integer is negative or too large to be an IPv4 IP address. >>> ipaddress.ip_address(3221225985) IPv4Address('192.0.2.1') >>> ipaddress.v4_int_to_packed(3221225985) b'\xc0\x00\x02\x01'

tempfile.mktemp(suffix='', prefix='tmp', dir=None) Deprecated since version 2.3: Use mkstemp() instead. Return an absolute pathname of a file that did not exist at the time the call is made. The prefix, suffix, and dir arguments are similar to those of mkstemp(), except that bytes file names, suffix=None and prefix=None are not supported. Warning Use of this function may introduce a security hole in your program. By the time you get around to doing anything with the file name it returns,

class collections.Counter([iterable-or-mapping]) A Counter is a dict subclass for counting hashable objects. It is an unordered collection where elements are stored as dictionary keys and their counts are stored as dictionary values. Counts are allowed to be any integer value including zero or negative counts. The Counter class is similar to bags or multisets in other languages. Elements are counted from an iterable or initialized from another mapping (or counter): >>> c = Counter()

xmlparser.SetParamEntityParsing(flag) Control parsing of parameter entities (including the external DTD subset). Possible flag values are XML_PARAM_ENTITY_PARSING_NEVER, XML_PARAM_ENTITY_PARSING_UNLESS_STANDALONE and XML_PARAM_ENTITY_PARSING_ALWAYS. Return true if setting the flag was successful.

Element.removeAttributeNode(oldAttr) Remove and return oldAttr from the attribute list, if present. If oldAttr is not present, NotFoundErr is raised.

classmethod datetime.combine(date, time) Return a new datetime object whose date components are equal to the given date object’s, and whose time components and tzinfo attributes are equal to the given time object’s. For any datetime object d, d == datetime.combine(d.date(), d.timetz()). If date is a datetime object, its time components and tzinfo attributes are ignored.

sys.getwindowsversion() Return a named tuple describing the Windows version currently running. The named elements are major, minor, build, platform, service_pack, service_pack_minor, service_pack_major, suite_mask, and product_type. service_pack contains a string while all other values are integers. The components can also be accessed by name, so sys.getwindowsversion()[0] is equivalent to sys.getwindowsversion().major. For compatibility with prior versions, only the first 5 elements are ret

HTTPConnection.putheader(header, argument[, ...]) Send an RFC 822-style header to the server. It sends a line to the server consisting of the header, a colon and a space, and the first argument. If more arguments are given, continuation lines are sent, each consisting of a tab and an argument.

PurePath.root A string representing the (local or global) root, if any: >>> PureWindowsPath('c:/Program Files/').root '\\' >>> PureWindowsPath('c:Program Files/').root '' >>> PurePosixPath('/etc').root '/' UNC shares always have a root: >>> PureWindowsPath('//host/share').root '\\'
