is_package(fullname) An abstract method to return a true value if the module is a package, a false value otherwise. ImportError is raised if the loader cannot find the module. Changed in version 3.4: Raises ImportError instead of NotImplementedError.

Element.getAttributeNS(namespaceURI, localName) Return the value of the attribute named by namespaceURI and localName as a string. If no such attribute exists, an empty string is returned, as if the attribute had no value.

curses.def_prog_mode() Save the current terminal mode as the “program” mode, the mode when the running program is using curses. (Its counterpart is the “shell” mode, for when the program is not in curses.) Subsequent calls to reset_prog_mode() will restore this mode.

path The entry’s full path name: equivalent to os.path.join(scandir_path, entry.name) where scandir_path is the scandir() path argument. The path is only absolute if the scandir() path argument was absolute. The path attribute will be of the same type (str or bytes) as the scandir() path argument. Use fsdecode() to decode byte filenames.

bytearray.decode(encoding="utf-8", errors="strict") Return a string decoded from the given bytes. Default encoding is 'utf-8'. errors may be given to set a different error handling scheme. The default for errors is 'strict', meaning that encoding errors raise a UnicodeError. Other possible values are 'ignore', 'replace' and any other name registered via codecs.register_error(), see section Error Handlers. For a list of possible encodings, see section Standard Encodings. Note Passing the enc

abstractmethod get_source(fullname) An abstract method to return the source of a module. It is returned as a text string using universal newlines, translating all recognized line separators into '\n' characters. Returns None if no source is available (e.g. a built-in module). Raises ImportError if the loader cannot find the module specified. Changed in version 3.4: Raises ImportError instead of NotImplementedError.

class tuple([iterable]) Tuples may be constructed in a number of ways: Using a pair of parentheses to denote the empty tuple: () Using a trailing comma for a singleton tuple: a, or (a,) Separating items with commas: a, b, c or (a, b, c) Using the tuple() built-in: tuple() or tuple(iterable) The constructor builds a tuple whose items are the same and in the same order as iterable‘s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If i

PurePath.parent The logical parent of the path: >>> p = PurePosixPath('/a/b/c/d') >>> p.parent PurePosixPath('/a/b/c') You cannot go past an anchor, or empty path: >>> p = PurePosixPath('/') >>> p.parent PurePosixPath('/') >>> p = PurePosixPath('.') >>> p.parent PurePosixPath('.') Note This is a purely lexical operation, hence the following behaviour: >>> p = PurePosixPath('foo/..') >>> p.parent PurePosixPath('foo')

enumerate(iterable, start=0) Return an enumerate object. iterable must be a sequence, an iterator, or some other object which supports iteration. The __next__() method of the iterator returned by enumerate() returns a tuple containing a count (from start which defaults to 0) and the values obtained from iterating over iterable. >>> seasons = ['Spring', 'Summer', 'Fall', 'Winter'] >>> list(enumerate(seasons)) [(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')] >>

turtle.undobufferentries() Return number of entries in the undobuffer. >>> while undobufferentries(): ... undo()
