How to return a string value with ncurses?

Question

I've tried win.inch(y,x) and win.instr(y,x), even win.getch() and win.getkey(). None can achieve the detective effect? I've searched through stackoverflow and google, but so far I didn't find the solution. I've already read the curses manual of python. But still can't solve this.

My code:

import curses

stdscr = curses.initscr()
stdscr.addstr(1,1,'x')
if stdscr.inch(1,1) == 'x':
    stdscr.addstr(2,1,'success')
    stdscr.refresh()

stdscr.getch()
curses.endwin()

I've run this piece of code, but no "successs" was show on the screen. I've debug my code for 4 hours last night. And I'm sure I was stuck at this value judge claim " if stdscr.inch(1,1,) == 'x': ". How could I realize my purpose to see if there is a specific string at a coordinate and then do the correspond action?

curses.window.inch returns an int, not a str.

The following line:

if stdscr.inch(1, 1) == 'x':

should be:

if stdscr.inch(1, 1) & 0xff == ord('x'):

or using instr (without specifying length, instr returns a string that start at the given position to the end of the line):

if stdscr.instr(1, 1, 1) == 'x':
