did i do it right?

for index in range(x_training.shape[0]):
    if get_emotion(y_training[index, :]) == "sad" or get_emotion(y_training[index, :]) == "happy":
        emoX_training = x_training[index, :]
        emoY_training = y_training[index, :]
for index in range(x_testing.shape[0]):
    if get_emotion(y_testing[index, :]) == "sad" or get_emotion(y_testing[index, :]) == "happy":
        emoX_testing = x_testing[index, :]
        emoY_testing = y_testing[index, :]

print(emoX_training.shape)
print(emoY_training.shape)

print(emoX_testing.shape)
print(emoY_testing.shape)
