Back in 7 we saw several different ways of saving and loading data from disk, and in this chapter we have seen how to interact with data types that hold their data on disk rather than in memory For DBM les the shelve module is very convenient since it stores string object items If we want complete control we can of course use any of the underlying DBMs directly One nice feature of the shelve module and of the DBMs generally is that they use the dictionary API, making it easy to retrieve, add, edit, and remove items, and to convert programs that use dictionaries to use DBMs instead One small inconvenience of DBMs is that for relational data we must use a separate DBM le for each key value table, whereas SQLite stores all the data in a single le For SQL databases, SQLite is useful for prototyping, and in many cases in its own right, and it has the advantage of being supplied with Python as standard We have seen how to obtain a database object using the connect() function and how to execute SQL queries (such as CREATE TABLE, SELECT, INSERT, UPDATE, and DELETE) using the database cursor s execute() method Python offers a complete range of choices for disk-based and in-memory data storage, from binary les, text les, XML les, and pickles, to DBMs and SQL

Write an interactive console program to maintain a list of bookmarks For each bookmark keep two pieces of information: the URL and a name Here is an example of the program in action:

From the Windows client application, use the Add Service Reference option to create a proxy for the service Create a simple form with two Web TextBoxes and two Buttons Assign the rst button to call the service, passing the values from the TextBoxes as arguments Assign the second button to refresh the local instance of the service proxy Your client code might look similar to Listing 102

Each CustomItem is responsible for adapting its behavior to the interaction methods available on a target device A CustomItem subclass needs to call the method getInteractionModes to inspect the interaction modes that are supported by a particular device This method returns a bit mask of the supported modes with bits set or unset for the following modes:

(A)dd (E)dit (L)ist (R)emove (Q)uit [l]: e Number of bookmark to edit: 2 URL [http://wwwriverbankcomputingcom]: Name [PyQt]: PyQt (Python bindings for GUI library)

The program should allow the user to add, edit, list, and remove bookmarks To make identifying a bookmark for editing or removing as easy as possible, list the bookmarks with numbers and ask the user to specify the number of the bookmark they want to edit or remove Store the data in a DBM le using the shelve module and with names as keys and URLs as values Structurally the program is very similar to dvds-dbmpy, except for the find_bookmark() function which is much simpler than find_dvd() since it only has to get an integer from the user and use that to nd the corresponding bookmark s name As a courtesy to users, if no protocol is speci ed, prepend the URL the user adds or edits with http:// The entire program can be written in fewer than 100 lines (assuming the use of the Console module for Consoleget_string() and similar) A solution is provided in bookmarkspy

Run the application and pass functional arguments (for example, 10 and 5) Assuming you ve coded the sample correctly, the result of the division should be displayed (for example, 2) Now change the denominator value to zero and retry the call You should see a result similar to Figure 101

Regexes are used for ve main purposes:

[ Team LiB ]

A regular expression is a compact notation for representing a collection of strings What makes regular expressions so powerful is that a single regular expression can represent an unlimited number of strings providing they meet the regular expression s requirements Regular expressions (which we will mostly call regexes from now on) are de ned using a mini-language that is completely different from Python but Python includes the re module through which we can seamlessly create and use regexes

Parsing: identifying and extracting pieces of text that match certain criteria regexes are used for creating ad hoc parsers and also by traditional parsing tools Searching: locating substrings that can have more than one form, for example, nding any of petpng , petjpg , petjpeg , or petsvg while avoiding carpetpng and similar Searching and replacing: replacing everywhere the regex matches with a string, for example, nding bicycle or human powered vehicle and replacing either with bike Splitting strings: splitting a string at each place the regex matches, for example, splitting everywhere colon-space or equals ( : or = ) occurs Validation: checking whether a piece of text meets some criteria, for example, contains a currency symbol followed by digits The regexes used for searching, splitting, and validation are often fairly small and understandable,making them ideal for these purposes However, although

Finally, return the denominator to a nonzero value and call the service again Although the call would normally be successful, the call fails, receivwith a message similar to ing a Figure 102
