The Haskell Platform is a collection of software-packages, tools and libraries, which is to create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: “Batteries included”.

The quality of a programming language itself is only one component in the ability of application writers to get the job done. Programming languages can succeed or fail based on the breadth and quality of their library collection.
