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.

ctypes.sizeof(obj_or_type) Returns the size in bytes of a ctypes type or instance memory buffer. Does the same as the C sizeof operator.

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')

locale.getlocale(category=LC_CTYPE) Returns the current setting for the given locale category as sequence containing language code, encoding. category may be one of the LC_* values except LC_ALL. It defaults to LC_CTYPE. Except for the code 'C', the language code corresponds to RFC 1766. language code and encoding may be None if their values cannot be determined.

strip_dirs() This method for the Stats class removes all leading path information from file names. It is very useful in reducing the size of the printout to fit within (close to) 80 columns. This method modifies the object, and the stripped information is lost. After performing a strip operation, the object is considered to have its entries in a “random” order, as it was just after object initialization and loading. If strip_dirs() causes two function names to be indistinguishable (they are

pdb.post_mortem(traceback=None) Enter post-mortem debugging of the given traceback object. If no traceback is given, it uses the one of the exception that is currently being handled (an exception must be being handled if the default is to be used).

xmlparser.buffer_used If buffer_text is enabled, the number of bytes stored in the buffer. These bytes represent UTF-8 encoded text. This attribute has no meaningful interpretation when buffer_text is false.
