「[2,3,4,1]」を 「2 3 4 1」 と出力したい場合(python3)

More than 1 year has passed since last update.

HackerRankでたまーにある出力形式で困る

sample outputをみると

2 3 4 1

と書いてある。

何も考えずにリストを普通に出力すると…

コード
print(arr)

出力結果

いや、もうこれは正解やーーん!!笑

これでは、だめらしいですね…

解決策

コード
print(' '.join(map(str,arr2)))

出力結果

[追記]
コメントをいただいて、かなり簡単な方法があったので、追記します。

コード
arr = [2, 3, 4, 1]
print(*arr)
出力結果
2 3 4 1

めっちゃ簡単ですね!!
