Search Engine Traffic Guide
You have seen one example of a CGI script processing preset environment variables. We now use an environment variable to supply data (e.g., client's name, search-engine query, etc.) to a CGI script. This section presents the environment variable QUERY_STRING that provides such a mechanism. The QUERY_STRING variable contains extra information that is appended to a URL in a GET request, following a question mark ( ). For example, the URL
Let's write a program that analyzes text documents and counts how many times each word appears in the document. This kind of analysis is sometimes used as a crude measure of the style similarity between two documents and is also used by automatic indexing and archiving programs (such as Internet search engines).
Finding a Python package or module can be as easy as entering the functionality you're looking for, like mp3 tags and Python into a search engine, and then sorting through the results. If you're lucky, you may find the module you need packaged for your OS with an executable Windows or Mac OS X installer or a package for your Linux distribution.
If you wish to use the Eclipse IDE for development, you should definitely download the Google App Engine plug-in using the link provided earlier in the chapter. You should also use the PyDev plug-in which is available at http pydev.sourceforge.net . For the purposes of this section, we used Eclipse Galileo and started a new project named JythonGAE as a Google Web Application. When creating the project, make sure you check the box for using Google App Engine and uncheck the Google Web Toolkit option. You will find that Eclipse creates a directory structure for your application that is much the same as the project template that is included with the Google App Engine SDK. When you are ready to deploy the application, you can choose to use the Google App Engine development environment or deploy to the cloud. You can run the application by right-clicking on the project and choosing Run As option and then choose the Google Web Application option. The first time you run the application you...
The urllib package provides a high-level interface for writing clients that need to interact with HTTP servers, FTP servers, and local files. Typical applications include scraping data from web pages, automation, proxies, web crawlers, and so forth. This is one of the most highly configurable library modules, so every last detail is not presented here. Instead, the most common uses of the package are described. The urllib.robotparser module (robotparser in Python 2) is used to fetch and parse the contents of 'robots.txt' files used to instruct web crawlers. Consult the online documentation for further usage information.
There are many types of programs that not only read strings as input and write strings as output, but also perform operations on strings. Word processing programs, for example, manipulate large amounts of text, and thus work extensively with strings. Email programs and search engines are other examples of programs that perform operations on strings.
Now visit your favorite search engine and look up some tutorials on UML. There are dozens, so find the one that suits your preferred method of study. Sketch some class diagrams or a sequence diagram for the objects you identified earlier. Don't get too hung up on memorizing the syntax (after all, if it is important, you can always look it up again), just get a feel for the language. Something will stay lodged in your brain, and it can make communicating a bit easier if you can quickly sketch a diagram for your next OOP discussion.
I couldn't possibly have done the job without an impressive array of technology to help me. I don't know the names of all the people I should thank for the Internet, ADSL, and Google's search engines, which, together, let me look things up so easilyor for many of the other hardware and software technologies cooperating to amplify my productivity. But, I do know I couldn't have made it without Theo de Raadt's OpenBSD operating system, Steve Jobs' inspiration behind Mac OS X and the iBook G4 on which I did most of the work, Bram Moolenaar's VIM editor, and, of course, Guido van Rossum's Python language. So, I'll single out Theo, Steve, Bram, and Guido for special thanks
Search Engine Optimization Overview
This is the 2nd volume of a 9 volume series called the Webmasters Toolbox package. Search engines are the number one way that internet users find websites. In most cases, a listing in a search engine is free. So, it's no surprise that Search Engine Optimization SEO is often the first priority when marketing a website.
