+Python の開発は、1990 年ごろから開始されています。
+開発者の Guido van Rossum は教育用のプログラミング言語「ABC」の開発に参加していましたが、ABC は実用上の目的にはあまり適していませんでした。
+このため、Guido はより実用的なプログラミング言語の開発を開始し、英国 BBS 放送のコメディ番組「モンティ パイソン」のファンである Guido はこの言語を「Python」と名づけました。
+このような背景から生まれた Python の言語設計は、「シンプル」で「習得が容易」という目標に重点が置かれています。
+多くのスクリプト系言語ではユーザの目先の利便性を優先して色々な機能を言語要素として取り入れる場合が多いのですが、Python ではそういった小細工が追加されることはあまりありません。
+言語自体の機能は最小限に押さえ、必要な機能は拡張モジュールとして追加する、というのが Python のポリシーです。
