To find the index, there is the function, example: Let’s retrieve the index value of the largest item in the list: Because the two lists are parallel, the index number of the highest grade in the “grades” list is the same as the index number of the student who earned that grade in the “students” list. The enumerate() function splits our list into two lists: index numbers and values. To find the index, there is the function index(), example: >>> l.index(max(l)) 2 Note: this function only returns the first index found. Turns out there is no built-in argmax function for Python list! The interesting bit of behavior here can be found in the condition that selects a new maximum: if item > maximum:. リストの最大値や最小値を取得するには、max()、min()を使います。またその時のインデックスはindex()を組み合わせると取得することができます。ただ、最大値が複数ある場合は注意が必要です。本記事ではそのような場合も含めて、これらの使い方の基本についてまとめています。 Through indexing, you can retrieve an item or range of items from a list.
