thanks,
actually i'm writing a game like mine,the pertainign code is:

def mark():
	"""mark the bomb"""
	(row, col) = gb.scrn.getyx()
	x = gb.scrn.inch(row,col)
	if x == 'F':
		gb.scrn.addch(row,col, 'X',curses.color_pair(3))
	else:
		gb.scrn.addch(row,col, 'F',curses.color_pair(3))

	gb.scrn.move(row,col)
	gb.scrn.refresh()

the situation is x never equals 'F', even when it really is!
I checked the mannual and found the return value of inch() consists
the actual character(low 8bits)
and the attributes, so I tried the following: (x<<24)>>24,cause I
guess the int is 32bits long.
but it still doesn't work :(
