Callableという概念

0
Last updated at Posted at 2026-04-15

結論

  • callable（呼び出し可能）
    • （）を後ろに持ってくることができる
  • Subscritable
    • []を後ろに持ってくることができる

Numpy配列は、SubscritableだがCallableではない

bins = np.arange(0, 1.05, 0.05)

ダメな例

bins(1)
#以下のようなErrorが出力される
TypeError: 'numpy.ndarray' object is not callable
  • ダメな理由：Numpy配列に対して関数（）を呼び出そうとした
    良い例
bin_width[1]
#Errorのない出力結果
bin_width[1]
