i have class i've created, called sprite: var sprite = function sprite() { = this; that.xpos = 0; that.ypos = 0; … that.image = null; this.render =function() { … } this.setimage(filename) { that.image = new image(); that.image.src = filename; } } and create array of objects: var names=[ {filename:"a1.png"}, {filename:"a2.png"}, {filename:"a3.png"}, {filename:"a4.png"} ]; var objs = []; for(var l=0;l<names.length;l++) { objs.push({}); objs[l] = new sprite(); … setimage(names[l]); } every object in array point same image (with same image file.) can tell me i'm doing wrong here? is there better way can this? thanks. your setimage(names[l]); in loop seems overwriting hence same image, try doing like: var sprite = function sprite() { = this; that.xpos = 0; that.ypos = 0; that.image = null; this.setimage = function(filename) { that.image = new image(); that.image.

it typical use with statement open file file handle cannot leaked: with open("myfile") f: … but if exception occurs somewhere within open call? open function not atomic instruction in python interpreter, it's entirely possible asynchronous exception such keyboardinterrupt thrown* @ moment before open call has finished, after system call has completed. the conventional way of handle (in, example, posix signals) use masking mechanism : while masked, delivery of exceptions suspended until later unmasked. allows operations such open implemented in atomic way. such primitive exist in python? [*] 1 might it's doesn't matter keyboardinterrupt since program die anyway, not true of programs. it's conceivable program might choose catch keyboardinterrupt on top level , continue execution, in case leaked file handle can add on time. i not think possible mask exceptions , can mask signals not exceptions . in case keyboardinterrupt

i using avcapture+camera portrait mode capture image. when display captured image, fine--looks fine. when convert jpeg representation , convert base64 string server , server stored it, "rotated" already. so checked image orientation before sending server: uiimageorientation.right(so there way capture image using portrait mode captured image orientation up? well, doubt after digging). after server got image, did not anything, ignored metadata orientation guess. since image captured looks fine, want preserve how image like. however, want set image orientation up. if set image orientation, image not right anymore. so there way set orientation without causing image rotated or after setting orientation up, how keep orientation rotate actual image make right? - (uiimage *)removerotationforimage:(uiimage*)image { if (image.imageorientation == uiimageorientationup) return image; uigraphicsbeginimagecontextwithoptions(image.size, no, image.scale); [image d

this code printing 1 2 4 5..my question why p not updated new array @ 3rd iteration p = [1, 2, [1, 2, 3], 4, 5] each in p: if type(each) == int: print each else: p = each actually precise when debugged code saw updating value of p each variable not reinitialised again. because of if type(each) == int: line. third element list ( [1, 2, 3] ) , not int, doesn't print anything. now comes changing p variable: p name object, not object itself. if p = each inside loop, doesn't affect original object you're looping through, changes name p local name, points different object. round of loop ends, loop continues business original object looping through. so, notice p = each doesn't change existing object (the p you're looping through), creates new local name p points value of each . what want this: p = [1, 2, [1, 2, 3], 4, 5] each in p: if isinstance(each, list): x in each: print x else: print
