For example, !addstr displays a string at the current cursor location in the stdscr window, while !mvaddstr moves to a given y,x coordinate first before displaying the string. !waddstr is just like !addstr, but allows specifying a window to use instead of using stdscr by default. !mvwaddstr allows specifying both a window and a coordinate.\n\nFortunately the Python interface hides all these details. stdscr is a window object like any other, and methods such as ~curses.window.addstr accept multiple argument forms. Usually there are four different forms.\n\nAttributes allow displaying text in highlighted forms such as boldface, underline, reverse code, or in color. They'll be explained in more detail in the next subsection.\n\nThe ~curses.window.addstr method takes a Python string or bytestring as the value to be displayed. The contents of bytestrings are sent to the terminal as-is. Strings are encoded to bytes using the value of the window's ~window.encoding attribute; this defaults to the default system encoding as returned by locale.getencoding.\n\nThe ~curses.window.addch methods take a character, which can be either a string of length 1, a bytestring of length 1, or an integer.\n\nConstants are provided for extension characters; these constants are integers greater than 255. For example, ACS_PLMINUS is a +/- symbol, and ACS_ULCORNER is the upper left corner of a box (handy for drawing borders). You can also use the appropriate Unicode character.\n\nWindows remember where the cursor was left after the last operation, so if you leave out the y,x coordinates, the string or character will be displayed wherever the last operation left off. You can also move the cursor with the move(y,x) method. Because some terminals always display a flashing cursor, you may want to ensure that the cursor is positioned in some location where it won't be distracting; it can be confusing to have the cursor blinking at some apparently random location. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
