【Python】List append()とextend()の違い

Last updated at Posted at 2021-10-03

append()とextend()の違いをちょっと比較します。

append()

student_id = [1, 2, 3]
student_id.append([4, 5])
print(student_id) #[1, 2, 3, [4, 5]]

listをappend()と実行したら、listのまま格納されます。

extend()

student_id = [1, 2, 3]
student_id.extend([4, 5])
print(student_id) #[1, 2, 3, 4, 5]

listをextend()と実行したら、listのelementを取り出し、格納されます。

以上、簡単なメモでした!
