stat.S_IFMT(mode) Return the portion of the file’s mode that describes the file type (used by the S_IS*() functions above).

exc_msg The exception message generated by the example, if the example is expected to generate an exception; or None if it is not expected to generate an exception. This exception message is compared against the return value of traceback.format_exception_only(). exc_msg ends with a newline unless it’s None. The constructor adds a newline if needed.

DatagramTransport.abort() Close the transport immediately, without waiting for pending operations to complete. Buffered data will be lost. No more data will be received. The protocol’s connection_lost() method will eventually be called with None as its argument.

with_prefixlen

@abc.abstractclassmethod A subclass of the built-in classmethod(), indicating an abstract classmethod. Otherwise it is similar to abstractmethod(). This special case is deprecated, as the classmethod() decorator is now correctly identified as abstract when applied to an abstract method: class C(metaclass=ABCMeta): @classmethod @abstractmethod def my_abstract_classmethod(cls, ...): ... New in version 3.2. Deprecated since version 3.3: It is now possible to use classmet

persistent_id(obj) Do nothing by default. This exists so a subclass can override it. If persistent_id() returns None, obj is pickled as usual. Any other value causes Pickler to emit the returned value as a persistent ID for obj. The meaning of this persistent ID should be defined by Unpickler.persistent_load(). Note that the value returned by persistent_id() cannot itself have a persistent ID. See Persistence of External Objects for details and examples of uses.

class email.headerregistry.ParameterizedMIMEHeader MOME headers all start with the prefix ‘Content-‘. Each specific header has a certain value, described under the class for that header. Some can also take a list of supplemental parameters, which have a common format. This class serves as a base for all the MIME headers that take parameters. params A dictionary mapping parameter names to parameter values.

textwrap.wrap(text, width=70, **kwargs) Wraps the single paragraph in text (a string) so every line is at most width characters long. Returns a list of output lines, without final newlines. Optional keyword arguments correspond to the instance attributes of TextWrapper, documented below. width defaults to 70. See the TextWrapper.wrap() method for additional details on how wrap() behaves.

bytearray.islower() Return true if there is at least one lowercase ASCII character in the sequence and no uppercase ASCII characters, false otherwise. For example: >>> b'hello world'.islower() True >>> b'Hello world'.islower() False Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.

Node.isSameNode(other) Returns true if other refers to the same node as this node. This is especially useful for DOM implementations which use any sort of proxy architecture (because more than one object can refer to the same node). Note This is based on a proposed DOM Level 3 API which is still in the “working draft” stage, but this particular interface appears uncontroversial. Changes from the W3C will not necessarily affect this method in the Python DOM interface (though any new W3C API
