Question

I am developing one app in python curses. I am using getch() method to get pressed keys.
But I can see pressed keys on screen. I can move cursor whenever I want, but after cursor I can see what user typed.

Of course, I can erase and redraw the whole screen after every pressed key, but it’s blinking – that’s distrubing.

Any idea how to get rid of these pressed keys? Thank you

Initialize the curses class in the following way, it will solve the problem.

class curses_screen:
    def __enter__(self):
        self.stdscr = curses.initscr()
        curses.cbreak()
        curses.noecho()
        self.stdscr.keypad(1)
        SCREEN_HEIGHT, SCREEN_WIDTH = self.stdscr.getmaxyx()
        return self.stdscr
    def __exit__(self,a,b,c):
        curses.nocbreak()
        self.stdscr.keypad(0)
        curses.echo()
        curses.endwin()

with curses_screen() as stdscr:
    """
    Execution code plush getch code here
    """
