pydocのパラメータをコメントする方法

Question

関数のパラメータをpydocライブラリで認識できるようにコメントする方法はありますか？

つまり、pydocのdocstringは何ですか？

Answer 1

pydocはdocstring内の "構造化"要素を認識せず、docstringをそのまま出力します。例については、PEP 0257を参照してください。

あなたが「フォーマットした」ドキュメントをしたい場合は、例えば機能のための

パラメータは関数ドキュメンテーション文字列で文書化する必要がある、などSphinxとして、別のドキュメントジェネレータを使用する必要があります。ここでthis answerから取った例である：あなたがより多くのパラメータ記述子を持つ再編テキストを利用したい場合はここで

は別の、より明示的な例であり、このよう:type param:や:rtype:としてfrom here

Use it to import very obvious functions.

あなたは（GoogleまたはNumpyなど）、のような異なるdocstring形式を使用することもできます。を使用して、ドキュメントストリングをより明確にします。

希望すると便利です。
