@functools.lru_cache(maxsize=128, typed=False) Decorator to wrap a function with a memoizing callable that saves up to the maxsize most recent calls. It can save time when an expensive or I/O bound function is periodically called with the same arguments. Since a dictionary is used to cache results, the positional and keyword arguments to the function must be hashable. If maxsize is set to None, the LRU feature is disabled and the cache can grow without bound. The LRU feature performs best wh

xml.sax.handler.property_xml_string value: "http://xml.org/sax/properties/xml-string" data type: String description: The literal string of characters that was the source for the current event. access: read-only

sys.builtin_module_names A tuple of strings giving the names of all modules that are compiled into this Python interpreter. (This information is not available in any other way — modules.keys() only lists the imported modules.)

os.sched_rr_get_interval(pid) Return the round-robin quantum in seconds for the process with PID pid. A pid of 0 means the calling process.

cmath.pi The mathematical constant π, as a float.

Node.namespaceURI The namespace associated with the element name. This will be a string or None. This is a read-only attribute.

View.Execute(params) Execute the SQL query of the view, through MSIViewExecute(). If params is not None, it is a record describing actual values of the parameter tokens in the query.

regex.subn(repl, string, count=0) Identical to the subn() function, using the compiled pattern.

email.encoders.encode_quopri(msg) Encodes the payload into quoted-printable form and sets the Content-Transfer-Encoding header to quoted-printable [1]. This is a good encoding to use when most of your payload is normal printable data, but contains a few unprintable characters.

typing.get_type_hints(obj) Return type hints for a function or method object. This is often the same as obj.__annotations__, but it handles forward references encoded as string literals, and if necessary adds Optional[t] if a default value equal to None is set.
