i think easy question experienced numpy users. i have score matrix. raw index corresponds samples , column index corresponds items. example, score_matrix = [[ 1. , 0.3, 0.4], [ 0.2, 0.6, 0.8], [ 0.1, 0.3, 0.5]] i want top-m indices of items each samples. want top-m scores. example, top2_ind = [[0, 2], [2, 1], [2, 1]] top2_score = [[1. , 0.4], [0,8, 0.6], [0.5, 0.3]] what best way using numpy? i'd use argsort() : top2_ind = score_matrix.argsort()[:,::-1][:,:2] that is, produce array contains indices sort score_matrix : array([[1, 2, 0], [0, 1, 2], [0, 1, 2]]) then reverse columns ::-1 , take first 2 columns :2 : array([[0, 2], [2, 1], [2, 1]]) then similar regular np.sort() values: top2_score = np.sort(score_matrix)[:,::-1][:,:2] which following same mechanics above, gives you: array([[ 1. , 0.4], [ 0.8, 0.6], [ 0.5, 0.3]])

i have following works fine 2 conditions: var value = this.value === "foo" ? function(d) { return d.foo; } : function(d) { return d.bar; }; what doing wrong when try expand above following using if-else ? var value = if (this.value === "foo") { function(d) { return d.foo; }; } else if (this.value === "bar") { function(d) { return d.bar; }; } else { function(d) { return d.qux; }; } i'm happy stick operators or switching if-else : whatever more readable me. if cannot used on right-hand side of assignment statement (which part of why have conditional operator). instead, assign in each branch: var value; if (this.value === "foo") { value = function(d) { return d.foo; }; } else if (this.value === "bar") { value = function(d) { return d.bar; }; } else { value = function(d) { return d.qux; }; } ...
