i have 4 sublist in list below of length 38, want count number of 0 on each position. please how do it? [[01100000100000000001100001001110100000],[01100000100000000001100001001110100000], [01100000100000000001100001001110100000], [01100000100000000001100001001110100000]] the first index of 4 sublist 0000, hence number of 0 4. second index of 4 sublist 1111, hence number of 0 0. how want count 38 positions. it's not clear question if numbers lists or strings. assuming they're strings (otherwise use bin() ), i'd use zip() separate each position count() '0' : numbers = ['01100000100000000001100001001110100000', '01100000100000000001100001001110100000', '01100000100000000001100001001110100000', '01100000100000000001100001001110100000'] [digits.count('0') digits in zip(*numbers)]

i have array of records (custom data type) in haskell want aggregate based on each records' timestamp. in general terms each record looks this: data record = record { event :: string, time :: double, :: int, :: int } deriving (show, eq) i used double timestamp since same format used in tracefile. and parse them csv file array of records: [record] now i'm looking approximation of instantaneous events / time. want split array several arrays based on timestamp (say. every 1 seconds) , fold across each smaller array. the problem can't figure out how split array based on value of record. looking on hoogle found several functions splitevery , splitwhen , i'm lost. considered using splitwhen break list when, say, (mod time 0.1) == 0 , if worked remove elements it's splitting on (which don't want do). i should note records not evenly spaced in time. e.g. ...

i have 10 frames of wcdma complex samples in sigi scrambling code -- matlab gold code (1,1) , "sc" variable. np.correlate() gives clean correlation spikes expected in code below extremely slow. try use fftconvolve() in same code, detected no spikes present. fftconvolve() fast, have work. please tell me why not work? mat=scipy.io.loadmat('011.mat') scr=mat['sc'] o1 = np.correlate(sigi,scr,mode='valid') # o1=signal.fftconvolve(sigi,scr,mode='valid') plot(abs(o1)) cc=max(abs(o1)) print ' max peak = ', cc found answer. if conjugate of scr used both np.correlation() , signal.fftconvolve() give same answer. dont understand reason though?? scr=np.conjugate(scr[0,:]) o1=signal.fftconvolve(sigi,scr[::-1],mode='valid') gave same answer : scr=scr[0,:] o1=np.correlate(sigi,scr,mode='valid') at least, problem solved.

with angular's $resource promise able assign promise right variable , use out having assign results of promise varible in success function. wondering if can achieve same thing $q? example .service("rest", function($resource){ return { user: $resource( "http://some.com/url") } }) .controller("myctrl", function($scope, rest){ $scope.user = rest.user.get(); <-- want able $q }) short answer: no the $resource interface designed allow kind of 'futures' behaviour. when call .get() returns placeholder object filled data when it's available. because $resource internal angular factory, knows when trigger digest cycles makes seem can use $scope.user beginning. in actuality, won't populated data until there has been http response server. a promise on other hand, general purpose mechanism. doesn't know kind of placeholder object store it's values in when arrive. do...
