here i'm trying do: i want count letters frequency in sentence. here code in python far: for in line: if in my_count.keys(): my_count[i]+=1 else: my_count[i]=1 is there way fulfill same goal dict comprehension, same list comprehension? i have thought @ such : my_count = { x:(my_count[x]+=1) x in line if x in my_count else x:1 } but not pass syntax check (syntaxerror: invalid syntax @ +=). thanks , advices! counter in collections seems accomplish this. in [1]: line = 'the quick brown fox jumps on lazy dog' in [2]: collections import counter in [3]: c = counter(line) in [4]: c out[4]: counter({' ': 8, 'o': 4, 'e': 3, 'h': 2, 'r': 2, 'u': 2, 't': 2, 'a': 1, 'c': 1, 'b': 1, 'd': 1, 'g': 1, 'f': 1, 'i': 1, 'k': 1, 'j': 1, 'm': 1, 'l': 1, 'n': 1, 'q': 1, 'p':

i have nsarray of pfobjects , want fetch data related objects in array in 1 go, afterwards there no need make new call parse. how can this? my answer assuming array want contained in pfobject. can query object , use include key include array contained within key. pfquery *query = [pfquery querywithclassname:@"<object's class name>"]; [query wherekey:@"objectid" equalto:object.objectid]; [query includekey:@"<array key>"]; if objects in array have pointers other objects within them can use dot syntax fetch @ once. [query includekey@"<array key>.<pointer in object array key>"]; run query once set , should retrieve array of 1 object since objectids unique, within object array. [query findobjectsinbackgroundwithblock:^(nsarray *objects, nserror *error){ if(error){ // handle error }else{ if([objects count] > 0){ pfobject *o

i have used factanal function in r factor analysis on data set. viewing summary of output, see have access loading , other objects, interested in scores of factor analysis. how can scores when using factanal function? i attempted calculate scores myself: m <- t(as.matrix(factor$loadings)) n <- (as.matrix(dataset)) scores <- m%*%n and got error: error in m %*% n : non-conformable arrays which i'm not sure why, since double checked dimension of data , dimensionality in agreement. thanks help. ah. factormodel$loadings[,1] %*% t(dataset)

i trying process keydown event below code process first char of string , not able remove second char of string. private void game_keydown(object sender, keyeventargs e) { if(birdsarray[selectedindex].this_string.first()== (char)e.keydata) { birdsarray[selectedindex].this_string = birdsarray[selectedindex].this_string.remove(0, 1); this.validate(); } } in below code birdsarray array of panels, this_string string type of string object in birdsarray . the keydown event gives virtual key code of key pressed. keys.a if press a-key. tells key, not letter that's produced key. depends on active keyboard layout (it not in japan or russia example) , modifier keys down. shift being obvious example, producing either a or a . or alt which, when down, doesn't produce letter @ all. so code work accident if first letter of string capitalized. you'll run out of luck when rest not. a not match a . it pretty unclear me why need feat
