Pythonで「リストの要素を取得する」の動作を確認してみた

Posted at

概要

Pythonで「リストの要素を取得する」の動作を確認してみました。以下のページを参考にしました。

実装

以下のファイルを作成しました。

sample.py
colorlist = ["Red", "Blue", "Green"]
print(colorlist[0])
print(colorlist[1])
print(colorlist[2])
colorlist = ["Red", "Blue", "Green"]
print(colorlist[-1])
print(colorlist[-2])
print(colorlist[-3])
#colorlist = ["Red", "Blue", "Green"]
#print(colorlist[3])
print(colorlist[len(colorlist) - 1])
colorlist = ["Blue", "Red", "Green", "White", "Black"]
print("最初の要素は " + colorlist[0] + " です。")
print("最後の要素は " + colorlist[len(colorlist) - 1] + " です。")

以下のコマンドを実行しました。

$ python3 sample.py 
Red
Blue
Green
Green
Blue
Red
Green
最初の要素は Blue です。
最後の要素は Black です。

まとめ

何かの役に立てばと。
