static bytes.maketrans(from, to) static bytearray.maketrans(from, to) This static method returns a translation table usable for bytes.translate() that will map each character in from into the character at the same position in to; from and to must both be bytes-like objects and have the same length. New in version 3.1.

Logger.info(msg, *args, **kwargs) Logs a message with level INFO on this logger. The arguments are interpreted as for debug().

streamreader Stream writer and reader classes or factory functions. These have to provide the interface defined by the base classes StreamWriter and StreamReader, respectively. Stream codecs can maintain state.

bytes.capitalize() bytearray.capitalize() Return a copy of the sequence with each byte interpreted as an ASCII character, and the first byte capitalized and the rest lowercased. Non-ASCII byte values are passed through unchanged. Note The bytearray version of this method does not operate in place - it always produces a new object, even if no changes were made.

readall() Read and return all the bytes from the stream until EOF, using multiple calls to the stream if necessary.

class collections.UserDict([initialdata]) Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it be used for other purposes. In addition to supporting the methods and operations of mappings, UserDict instances provide the following attribute: data A real

class asyncio.Handle A callback wrapper object returned by AbstractEventLoop.call_soon(), AbstractEventLoop.call_soon_threadsafe(), AbstractEventLoop.call_later(), and AbstractEventLoop.call_at(). cancel() Cancel the call. If the callback is already canceled or executed, this method has no effect.

curses.newwin(nlines, ncols) curses.newwin(nlines, ncols, begin_y, begin_x) Return a new window, whose left-upper corner is at (begin_y, begin_x), and whose height/width is nlines/ncols. By default, the window will extend from the specified position to the lower right corner of the screen.

curses.tigetflag(capname) Return the value of the Boolean capability corresponding to the terminfo capability name capname. The value -1 is returned if capname is not a Boolean capability, or 0 if it is canceled or absent from the terminal description.

exception configparser.DuplicateOptionError Exception raised by strict parsers if a single option appears twice during reading from a single file, string or dictionary. This catches misspellings and case sensitivity-related errors, e.g. a dictionary may have two keys representing the same case-insensitive configuration key.
