+2 marksNumerical answer

What will be the output of the following code ?

python
from sklearn.neighbors import KNeighborsClassifier
X_train = [[1,100],[4,400],[5,500],[6,600],[8,800],[9,900],
           [11,1100],[12,1200],[15,1500], [18,1800],[19,1900]]
y_train = [0,0,1,1,1,2,2,2,2,2,2]


X_test = [[2,200]]


knn = KNeighborsClassifier(n_neighbors= len(y_train),
                           metric="euclidean",
                           weights= 'uniform')
knn.fit(X_train,y_train)


print(knn.predict(X_test))
