server_software If the origin_server attribute is set, this attribute’s value is used to set the default SERVER_SOFTWARE WSGI environment variable, and also to set a default Server: header in HTTP responses. It is ignored for handlers (such as BaseCGIHandler and CGIHandler) that are not HTTP origin servers. Changed in version 3.3: The term “Python” is replaced with implementation specific term like “CPython”, “Jython” etc.

aifc.setpos(pos) Seek to the specified frame number.

curses.initscr() Initialize the library. Return a WindowObject which represents the whole screen. Note If there is an error opening the terminal, the underlying curses library may cause the interpreter to exit.

class weakref.WeakKeyDictionary([dict]) Mapping class that references keys weakly. Entries in the dictionary will be discarded when there is no longer a strong reference to the key. This can be used to associate additional data with an object owned by other parts of an application without adding attributes to those objects. This can be especially useful with objects that override attribute accesses. Note Caution: Because a WeakKeyDictionary is built on top of a Python dictionary, it must no

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

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.

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.

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