You might not want to use all of the elements included in this particular puzzle graphic, but you still can work with it because it is vector art, called resizable at the Microsoft Of ce Online Clip Art And Media site. The value of this type of graphic is that you can break it into its components using the PowerPoint graphics tools and use only portions of it on a slide. Another advantage of this type of graphic is that you can resize it without ever losing its sharp, clear lines. Right-click the puzzle graphic you inserted on the slide, and on the shortcut menu, click Group, Ungroup. (If the Ungroup option doesn t appear on this shortcut menu, the clip art is not resizable.) If a Microsoft Of ce PowerPoint message box appears that reads, This is an imported picture, not a group. Do you want to convert it to a Microsoft Of ce Drawing Object click Yes. Right-click the graphic again, and then click Group, Ungroup again on the shortcut menu, which breaks up the graphic into its parts.

However, you cannot create directories under directories that don t yet exist themselves. If you want to create an entire structure of directories you must create them one by one from the top down.

Also, let s say you have a tuple with two numbers that you want to add: params = (1, 2) This is more or less the opposite of what we did previously. Instead of gathering the parameters, we want to distribute them. This is simply done by using the asterisk operator in the other end, that is, when calling the function rather than when defining it: >>> add(*params) 3 This works with parts of a parameter list, too, as long as the expanded part is last. You can use the same technique with dictionaries, using the double asterisk operator. Assuming that you have defined hello_3 as before, you can do the following: >>> params = {'name': 'Sir Robin', 'greeting': 'Well met'} >>> hello_3(**params) Well met, Sir Robin! Using the asterisk (or double asterisk) both when you define and call the function will simply pass the tuple or dictionary right through, so you might as well not have bothered: >>> def with_stars(**kwds): print kwds['name'], 'is', kwds['age'], 'years old' >>> def without_stars(kwds): print kwds['name'], 'is', kwds['age'], 'years old' >>> >>> Mr. >>> Mr. args = {'name': 'Mr. Gumby', 'age': 42} with_stars(**args) Gumby is 42 years old without_stars(args) Gumby is 42 years old

When you search for vector art graphics at the Microsoft Of ce Online Clip Art And Media site, you ll know that a graphic you nd is vector art if the search results box includes the term Resizable under Dimensions.

Note On Unix-related operating systems, Dir.mkdir accepts a second optional argument: an integer,

specifying the permissions for the directory. You can specify this in octal, as with 0666 or 0777, representing modes 666 and 777 respectively.

Click and delete any pieces of the group you don t want, and click and change the ll color of any of the objects if you want. When you have deleted the elements you don t want to keep and have made any other changes to resizable clip art, right-click somewhere on the graphic and select Group, Regroup from the shortcut menu this regroups the graphic into a single unit again instead of many separate smaller pieces. To resize a piece of resizable clip art on a slide, select it to display the sizing handles. Hold down the Shift key, and drag one of the corner sizing handles to change the graphic to the size you want. Holding down the Shift key while you drag a corner sizing handle preserves the proportions of the graphic as you resize it; otherwise, the image will be distorted.

Deleting a Directory Deleting a directory is similar to deleting a file:

Dir.delete("testdir")

As you can see, in with_stars, I use stars both when defining and calling the function. In without_stars, I don t use the stars in either place but achieve exactly the same effect. So the stars are only really useful if you use them either when defining a function (to allow a varying number of arguments) or when calling a function (to splice in a dictionary or a sequence).
