<p><code>for</code>ループは反復の最も一般的な形式の1つであり、<strong>反復回数が事前に分かっている場合に特に適しています</strong>。</p>
|
||||
<p>以下の関数は<code>for</code>ループを使用して<span class="arithmatex">\(1 + 2 + \dots + n\)</span>の合計を実行し、合計を変数<code>res</code>に格納します。Pythonでは、<code>range(a, b)</code>は<code>a</code>を含み<code>b</code>を除く区間を作成することに注意してください。つまり、<span class="arithmatex">\(a\)</span>から<span class="arithmatex">\(b−1\)</span>までの範囲で反復します。</p>

<p><strong><code>while</code>ループは<code>for</code>ループよりも柔軟性を提供します</strong>。特に、条件変数のカスタム初期化と各ステップでの変更が可能です。</p>

<p>例えば、以下のコードでは、条件変数<span class="arithmatex">\(i\)</span>が各ラウンドで2回更新されますが、これは<code>for</code>ループでは実装が不便です。</p>
