If raw_keys is False (default) this function will return a list of keys pressed. If raw_keys is True this function will return a ( keys pressed, raw keycodes ) tuple instead. Examples of keys returned: * ASCII printable characters: " ", "a", "0", "A", "-", "/" * ASCII control characters: "tab", "enter" * Escape sequences: "up", "page up", "home", "insert", "f1" * Key combinations: "shift f1", "meta a", "ctrl b" * Window events: "window resize" When a narrow encoding is not enabled: * "Extended ASCII" characters: "\xa1", "\xb2", "\xfe" When a wide encoding is enabled: * Double-byte characters: "\xa1\xea", "\xb2\xd4" When utf8 encoding is enabled: * Unicode characters: u"\u00a5", u'\u253c" Examples of mouse events returned: * Mouse button press: ('mouse press', 1, 15, 13), ('meta mouse press', 2, 17, 23) * Mouse drag: ('mouse drag', 1, 16, 13), ('mouse drag', 1, 17, 13), ('ctrl mouse drag', 1, 18, 13) * Mouse button release: ('mouse release', 0, 18, 13), ('ctrl mouse release', 0, 17, 23) N� window resizeT���rP rO r )�_started�_wait_for_input_readyr9 � parse_input�get_available_raw_inputr# r^ �append)rD �raw_keys�keys�raw�raw2rI rI rJ � get_input( s* , � zScreen.get_inputc C sL | j sg S | jg}| �� }|dur|�|� | jdur$|�| jj�� � |S )aG Return a list of integer file descriptors that should be polled in external event loops to check for user input.

The current implementation tries to avoid any assumptions about what the screen or event loop look like; it only deals with parsing keycodes and setting a timeout when an incomplete one is detected. `codes` should be a sequence of keycodes, i.e. bytes. A bytearray is appropriate, but beware of using bytes, which only iterates as integers on Python 3.
