exception BlockingIOError Raised when an operation would block on an object (e.g. socket) set for non-blocking operation. Corresponds to errno EAGAIN, EALREADY, EWOULDBLOCK and EINPROGRESS. In addition to those of OSError, BlockingIOError can have one more attribute: characters_written An integer containing the number of characters written to the stream before it blocked. This attribute is available when using the buffered I/O classes from the io module.

datetime.isoformat(sep='T') Return a string representing the date and time in ISO 8601 format, YYYY-MM-DDTHH:MM:SS.mmmmmm or, if microsecond is 0, YYYY-MM-DDTHH:MM:SS If utcoffset() does not return None, a 6-character string is appended, giving the UTC offset in (signed) hours and minutes: YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or, if microsecond is 0 YYYY-MM-DDTHH:MM:SS+HH:MM The optional argument sep (default 'T') is a one-character separator, placed between the date and time portions of the res

write(b) Write the given bytes-like object, b, and return the number of bytes written (always equal to the length of b in bytes, since if the write fails an OSError will be raised). Depending on the actual implementation, these bytes may be readily written to the underlying stream, or held in a buffer for performance and latency reasons. When in non-blocking mode, a BlockingIOError is raised if the data needed to be written to the raw stream but it couldn’t accept all the data without blocki

class traceback.FrameSummary(filename, lineno, name, lookup_line=True, locals=None, line=None) Represent a single frame in the traceback or stack that is being formatted or printed. It may optionally have a stringified version of the frames locals included in it. If lookup_line is False, the source code is not looked up until the FrameSummary has the line attribute accessed (which also happens when casting it to a tuple). line may be directly provided, and will prevent line lookups happening

sys.path_importer_cache A dictionary acting as a cache for finder objects. The keys are paths that have been passed to sys.path_hooks and the values are the finders that are found. If a path is a valid file system path but no finder is found on sys.path_hooks then None is stored. Originally specified in PEP 302. Changed in version 3.3: None is stored instead of imp.NullImporter when no finder is found.

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')

View.Close() Close the view, through MsiViewClose().

os.path.getmtime(path) Return the time of last modification of path. The return value is a number giving the number of seconds since the epoch (see the time module). Raise OSError if the file does not exist or is inaccessible. If os.stat_float_times() returns True, the result is a floating point number.
