pythonのリスト型の使い方(要素の連結、要素の取り出し:extend,スライス機能)

Last updated at Posted at 2024-03-18

リストの連結

>>> f_list = ['モモ', 'みかん', 'バナナ', 'イチジク', 'ブドウ']
>>> list_int = [-1, 1, 2, 4]
>>> f_list + list_int
['モモ', 'みかん', 'バナナ', 'イチジク', 'ブドウ', -1, 1, 2, 4]  

リストの連結。メソッド「extend」

>>> list_int.extend(f_list)
>>> print(list_int)
[-1, 1, 2, 4, 'モモ', 'みかん', 'バナナ', 'イチジク', 'ブドウ']

要素を取り出す。スライス機能

>>> list_f = [0,1,1,2,3,3,2,5,23,4,35]
>>> list_f[0:3]
[0, 1, 1]
>>> list_f[2:6]
[1, 2, 3, 3]
>>> list_f[:4]
[0, 1, 1, 2]
