Python 目前有四個產品級的實作（CPython、Jython、IronPython、
PyPy），以及一個處於早期開發階段的高效能實作 Pyston（

implementation/
），後者我們並沒有進一步涵蓋。我們也會在接下來的章節
提及幾個較為實驗性的實作。
本書主要針對 CPython，也就是最廣為使用的實作，通常我們會簡單稱之
「Python」。然而，一個語言與其實作之間的區別是很重要的。
CPython
傳統的 Python（即 CPython，通常單純稱為 Python）是最新、最穩固且
完整的 Python 產品級實作。它可被視為該語言的「參考實作（reference
implementation）」。 CPython 是一個編譯器、直譯器（interpreter），以及
一組內建的選擇性擴充模組，全都以標準的 C 編寫。CPython 可在其 C
編譯器符合 ISO/IEC 9899:1990 標準的任何平台上使用（也就是所有現
代、流行的平台）。在後面的「安裝」一節中，我們會解說如何下載並
