説明 オブジェクト指向スクリプト言語。

レビュー

Pythonはパワフルかつ高速なスクリプト言語。

Guido van Rossum氏の個人的なプロジェクトとして1991年にPython 0.90のソースコードが公開された。継承やクラスなどの機能を備えたオブジェクト指向のインタプリタ言語で、1994年にPython 1.0が、2000年にPython 2.0が公開された。

2008年にPython 3.0が公開されたが、Python 2.xと互換性の問題が存在し、長らく両方のバージョンが並立する状態が続くことになった。

AI・機械学習関連のライブラリが充実しているため2020年代は、世界トップクラスの人気を集めている。
