Function to reference class variable in Python -


i have program uses python windows extensions control mouse. i'm trying make function calls class variable (i think that's they're called).

anyways code looks this:

class mouse:      def move_mouse(self, pos):         """move mouse specified coordinates"""         (x, y) = pos         old_pos = self.get_position()         x =  x if (x != -1) else old_pos[0]         y =  y if (y != -1) else old_pos[1]         self._do_event(self.mouseeventf_move + self.mouseeventf_absolute, x, y, 0, 0)

it's called this: 

mouse = mouse(); position = (3,5); #some coordinate (where mouse on screen) mouse.move_mouse(position);

i'm wondering if can create function make easier call move_mouse() function. can call position have defined? can create work this:

positions = {"0": (123,432), "1": (312,123)}  def move(x);     mouse.move(positions[str(x)]);  >>>move(0)

and function should proceed move first entry in positions dictionary.

i can't stop getting error when run it. know why doesn't work?

one approach class attribute of pre-defined positions, when mouse.move_mouse called either tries retrieve pos dictionary, assuming it's key, or uses directly if isn't key:

class mouse:      positions = {'home': (0, 0), ...}      def move_mouse(self, pos):         """move mouse specified coordinates"""         x, y = self.positions.get(pos, pos)         ...

now both mouse.move_mouse('home') , mouse.move_mouse((0, 0)) have same effect.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
