What's The Short Way To Add Same Symbol At The Specified Place In Ncurses?

I want to add str '#' in ncurse screen,with coordinate x(5 to 24), y(23 to 42) which is a square. But I can't figure out a simple way to do it. I've tried: stdscr.addstr(range(23,

Solution 1:

First two arguments of addstr should be row, col as integer but your are passing list:

To make square to like this:

for x inrange(23,42): # horizontal c for y inrange(5,24): # verticale r
    stdscr.addstr(y, x, '#')        

To fill colors, blinking, bold etc you can use attribute filed in function:

from curses import *
def main(stdscr):
    start_color()
    stdscr.clear()  # clear above line. 
    stdscr.addstr(0, 0, "Fig: SQUARE", A_UNDERLINE|A_BOLD)    
    init_pair(1, COLOR_RED, COLOR_WHITE)
    init_pair(2, COLOR_BLUE, COLOR_WHITE)
    pair = 1
    for x in range(3, 3 + 5): # horizontal c 
      for y in range(4, 4 + 5): # verticale r
        pair = 1 if pair == 2 else 2
        stdscr.addstr(y, x, '#', color_pair(pair))
    stdscr.addstr(11, 0, 'Press Key to exit: ')
    stdscr.refresh()
    stdscr.getkey()    
wrapper(main)

Output:

Old-answer:

Do like this for diagonal:

for c, r in zip(range(23,42), range(5,24)) :
  stdscr.addstr(c, r, '#')      

Code example to fill diagonal:

code x.py

from curses import wrapper
def main(stdscr):
    stdscr.clear()  # clear above line. 
    for r, c in zip(range(5,10),range(10, 20)) :
      stdscr.addstr(r, c, '#')  
    stdscr.addstr(11, 0, 'Press Key to exit: ')
    stdscr.refresh()
    stdscr.getkey()

wrapper(main)

run: python x.py, then you can see:

To make a Square do like:

from curses import wrapper
def main(stdscr):
    stdscr.clear()  # clear above line. 
    for r in range(5,10):
      for c in range(10, 20):
        stdscr.addstr(r, c, '#')        
    stdscr.addstr(11, 0, 'Press Key to exit: ')
    stdscr.refresh()
    stdscr.getkey()

wrapper(main)

Output:

PS: from your code it looks like you wants to fill diagonal, so I edited answer later for square.
