elifステートメントを取得することはelif choice == "2":明らかに無効な構文ですが、elif choice == "1":動作し、次のコードは互いに正確に複製されていますか？

Pythonコードは適切にインデントする必要があります。

それ以外の場合は無効です。

これはおそらくPythonについて最初に学ぶことです（「ThinkinginPython」などの本を入手してください）。同時に、最も批判的なこと（少なくとも非ユーザーによる）。

有効なコード例：

if a == "1":
    echo "Apples"
elif b == "2":
    echo "Bananas"

インデントエラーによる無効なコード：

if a == "1":
echo "Apples"
elif b == "2":
    echo "Bananas"

タブとスペースを混在させています。そうしないでください。次のようにスクリプトを実行します。

python -tt yourscript.py

どこを見つけるために。すべてのタブをスペースに置き換え、インデントにスペースのみを使用するようにエディターを構成します。
