Cmd.precmd(line) Hook method executed just before the command line line is interpreted, but after the input prompt is generated and issued. This method is a stub in Cmd; it exists to be overridden by subclasses. The return value is used as the command which will be executed by the onecmd() method; the precmd() implementation may re-write the command or simply return line unchanged.

exception IndexError Raised when a sequence subscript is out of range. (Slice indices are silently truncated to fall in the allowed range; if an index is not an integer, TypeError is raised.)

name The name of the module the loader will handle.

handle_read() Called when the asynchronous loop detects that a read() call on the channel’s socket will succeed.

st_file_attributes Windows file attributes: dwFileAttributes member of the BY_HANDLE_FILE_INFORMATION structure returned by GetFileInformationByHandle(). See the FILE_ATTRIBUTE_* constants in the stat module.

bytearray.isupper() Return true if there is at least one uppercase alphabetic ASCII character in the sequence and no lowercase ASCII characters, false otherwise. For example: >>> b'HELLO WORLD'.isupper() True >>> b'Hello world'.isupper() 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'.

AbstractEventLoop.set_debug(enabled: bool) Set the debug mode of the event loop. New in version 3.4.2.

inspect.getinnerframes(traceback, context=1) Get a list of frame records for a traceback’s frame and all inner frames. These frames represent calls made as a consequence of frame. The first entry in the list represents traceback; the last entry represents where the exception was raised. Changed in version 3.5: A list of named tuples FrameInfo(frame, filename, lineno, function, code_context, index) is returned.

output A list of str objects with the formatted output of matching messages.

bytearray.hex() Return a string object containing two hexadecimal digits for each byte in the instance. >>> bytearray(b'\xf0\xf1\xf2').hex() 'f0f1f2' New in version 3.5.
