# Data Science - Binary Disorder Confusion matrix of binary classification. For binary classifications, a confusion matrix is a

I didnt get i have tried it like this y_true = [int(x) for x in input().split()] y_pred = [int(x) for x in input().split()] from sklearn.metrics import confusion_matrix from numpy as np y_pred = np.array(y_pred).reshape(-1 , 1) print(confusion_matrix(y_true, y_pred))

import numpy as np from sklearn.metrics import confusion_matrix y_true = [int(x) for x in input().split()] y_pred = [int(x) for x in input().split()] X = [] TL = float(0) TR = float(0) BL = float(0) BR = float(0) for x, y in zip(y_true, y_pred): if x == 1: if y == 1: TL += 1 else: BL += 1 elif x == 0: if y == 1: TR += 1 else: BR += 1 X.append(TL) X.append(TR) X.append(BL) X.append(BR) Y = np.array(X) Y = Y.reshape(2, 2) print(Y) I've tried this. And it works for all the cases..
