Python is a programming language. Thus programming languages like java, objective c, or c# that allow you to write full applications are not optimal choices. In addition, we assume that you have little or no prior programming experience. Thus interesting and challenging programming systems like Haskell, Lisp, or Prolog are best left for later. Consequently, we will use the Python programming language. There are specific reasons for this choice:

• Python is extremely widely used in practical
• Python has stable and clear semantics.
• Modules. There are tons of optional modules that others have written with useful functions and objects to simplify your programming tasks.
• NLTK. The Natural Language Toolkit is a freely available suite of modules tailored for working with language.
• Python is an object-oriented (OO) programming language, and using it requires that you at least understand what objects are.
