Return width of available window in characters. If detection fails, return value of standard width 80. Coordinate of the last character on a line is -1 from returned value.
Return available window height in characters or 25 if detection fails. Coordinate of the last line is -1 from returned value.
Wait for keypress and return character or a list of characters. Arrows and special keys generate a sequence of characters, so if there are extra symbols in input buffer, this function returns list.
..function:: page(content, [pagecallback=prompt])
Output content iterable, calling pagecallback function after each page with page number as a parameter. Default prompt() callback shows page number with ‘Press any key … ‘ prompt and waits for keypress.
Print msg to the screen without linefeed and flush the output.
Return hexadecimal representation of a key value returned by getch().
