Я новичок в Python и после учебника. Я немного озадачен тем, почему, когда я добавляю список в список, появляется «массив». Извините, если это простой вопрос, я новичок в Python.
from sklearn.datasets import load_iris
from sklearn import tree
iris = load_iris()
features = []
targets = []
for value in iris.data:
features.append(value)
for value in iris.target:
targets.append([value])
print(features)
print(targets)
Спасибо. Это вывод, который я получаю: (Я не уверен, почему он говорит массив --->)
