Language Processing and Python It is easy to get our hands on millions of words of text. What can we do with it, assuming we can write some simple programs?

In this chapter we'll address the following questions: What can we achieve by combining simple programming techniques with large quantities of text?

2 Getting Started with NLTK

How can we automatically extract key words and phrases that sum up the style and content of a text? What tools and techniques does the Python programming language provide for such work?

What are some of the interesting challenges of natural language processing? This chapter is divided into sections that skip between two quite different styles. In the "computing with language" sections we will take on some linguistically motivated programming tasks without necessarily explaining how they work.

In the "closer look at Python" sections we will systematically review key programming concepts. We'll flag the two styles in the section titles, but later chapters will mix both styles without being so up-front about it. We hope this style of introduction gives you an authentic taste of what will come later, while covering a range of elementary concepts in linguistics and computer science.

If you have basic familiarity with both areas, you can skip to 5 ; we will repeat any important points in later chapters, and if you miss anything you can easily consult the online reference material at http: If the material is completely new to you, this chapter will raise more questions than it answers, questions that are addressed in the rest of this book.

Texts and Words We're all very familiar with text, since we read and write it every day. Here we will treat text as raw data for the programs we write, programs that manipulate and analyze it in a variety of interesting ways. But before we can do this, we have to get started with the Python interpreter.

Under Unix you can run Python from the shell by typing idle if this is not installed, try typing python. The interpreter will print a blurb about your Python version; simply check that you are running Python 3.

In order to get the expected behavior of division you need to type: Now, let's begin by using Python as a calculator: This means the Python interpreter is waiting for another instruction.

Enter a few more expressions of your own. The preceding examples demonstrate how you can work interactively with the Python interpreter, experimenting with various expressions in the language to see what they do. Now let's try a nonsensical expression to see how the interpreter handles it: In Python, it doesn't make sense to end an instruction with a plus sign.

Now that we can use the Python interpreter, we're ready to start working with language data. Follow the instructions there to download the version required for your platform.The official home of the Python Programming Language.

Compound Data Types. Lists (known as arrays in other languages) are one of the compound data types that Python understands. Sources.

For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. Possible Duplicate: Python: What OS am I running on?

It is, however, technically possible to create an operating system centered on Python, that is; have only the very low level stuff in written in C and assembly and have most of the rest of the operating system written in Python.

Running Python files¶. When you have a lot of python code to run, you will want to save it into a file, so for instance, you can modify small parts of it (fix a bug) and re .

If you did everything correctly, you should now have a copy of the code in the cpython directory and two remotes that refer to your own GitHub fork (origin) and the official CPython repository (upstream).. If you want a working copy of an already-released version of Python, i.e., a version in maintenance mode, you can checkout a release regardbouddhiste.com instance, to checkout a working copy of Python.
