Python is packaged with a huge collection of classes and functions known as the standard library. This is why Python is often described as having batteries included, because you can take advantage of code written by Python experts to do everything from trigonometry to downloading web pages and sending e-mails. Libraries are organized into modules, or packages, with each having a specific purpose. You make use of these modules by importing them in the same way that the tank game (Listing 2-7) imported the Tank class. When you import something in Python, it will first look in the current directory for a corresponding Python file. If it doesn t find it, Python will look for a module in the standard library. Let s go over just a few of the modules in the standard library. We can t cover them all that would take a book in itself but if you need more information on any module, take a look at the docs that came with your Python distribution or browse them online at http:// docs.python.org/lib/lib.html.

Figure 7-33. Monitoring the progress of opening the backup file 7. When the backup file has opened, it will be displayed in Windows as though it were a normal drive (in this example, as a local disk with the drive letter Z), as shown in Figure 7-34. Search through the folders in the backup until you locate the file or files you want to restore.

It s worth pointing out that the configuration tool supports rudimentary searching: press the / key, and a search dialog appears (see Figure 5-4). The dialog asks for a CONFIG_ symbol, but it searches for both the CONFIG_ symbol and the corresponding prompt text that appears in the dialog. If you re new to

this configuration program, the output is a series of lines defining the value of variables, all of which start with CONFIG_. If you re familiar with the content and structure of the output file, you know the config var to be changed. But if you re just get starting, the search on the prompt string is more useful.

There are few ways in which you can import things from your own code, or from the standard library. Which method you use depends on how you want to access the classes and functions contained in the module. Modules can be imported with the import keyword, followed by the name of a module. For example, the following line would import a module called mymodule: import mymodule Importing a module this way creates a new namespace, which means that you will need to type the name of the module and a dot before any of the classes or functions that you use. For instance, if there were a function in mymodule called myfunction, you would call it like this: mymodule.myfunction() This is the usual way of importing modules from the standard library, because it keeps things in each module separate; if you had another function called myfunction in a different module, there would be no confusion as to which function is being called. It is also possible to import specific classes or functions from a module, using the from statement. The following line imports myclass from mymodule to the current namespace: from mymodule import myclass Use this method if you just want a few things from the module and you know that their names won t conflict with anything else in your script. You can import several classes, functions, and so forth by adding a comma between each one. So from mymodule import myclass, myfunction would import two things from the mymodule class.

Figure 7-34. Viewing the contents of the backup file 8. Drag and drop the file or files you want to restore anywhere on your computer, or copy them to a USB flash drive or other device if that s easier for you.
