As you saw in 5, the rst ve slides of your presentation accomplish the crucial work of orienting the audience to your story and making the experience personal and relevant to them. When you import your headlines into PowerPoint, an additional slide is inserted in front of these ve slides a Title slide is automatically created from your title and byline, as shown in Figure 7-2. Now you will sketch illustrations for the Title slide along with the Act I slides to powerfully complement the clear and coherent ow of ideas you set in motion in the beginning of your story.

using each, which you first used in the previous section on arrays, and passes the value into letter, which is then printed to the screen.

Note As you ve used print, rather than puts, the letters are printed one after another on the same line,

If you re using a Tablet PC, as you work through this chapter, you ll always review the slides to sketch in Slide Sorter view rst, then click on an individual slide to sketch it in Normal view, and then return to Slide Sorter view to review your work. If you re using a paper storyboard, sort the printouts of slides in whatever way works best for you.

As with lower, strip can be useful when comparing input to stored values. Let s return to the user name example from the section on lower, and let s say that the user inadvertently types a space after his name: >>> names = ['gumby', 'smith', 'jones'] >>> name = 'gumby ' >>> if name in names: print 'Found it!' ... >>> if name.strip() in names: print 'Found it!' ... Found it! >>> You can also specify which characters are to be stripped, by listing them all in a string parameter: >>> '*** SPAM * for * everyone!!! ***'.strip(' *!') 'SPAM * for * everyone' Stripping is only performed at the ends, so the internal asterisks are not removed. In Appendix B: lstrip, rstrip.

It might also be useful to test if something is included in the set of objects specified by the range. For example, with your ('A'..'Z') range, you can check to see if R is within the range, using the include method, like so:

print "R is within A to Z!" if ('A'..'Z').include ('R')

R is within A to Z!

Being a lowercase letter, however, r is not:

Similar to replace, translate replaces parts of a string, but unlike replace, translate only works with single characters. Its strength lies in that it can perform several replacements simultaneously, and can do so more efficiently than replace. There are quite a few rather technical uses for this method (such as translating newline characters or other platform-dependent special characters), but let s consider a simpler (although slightly more silly) example. Let s say you want to translate a plain English text into one with a German accent. To do this, you must replace the character c with k, and s with z. Before you can use translate, however, you must make a translation table. This translation table is a full listing of which characters should be replaced by which. Because this table (which is actually just a string) has 256 entries, you won t write it out yourself: You ll use the function maketrans from the string module. The maketrans function takes two arguments: two strings of equal length, indicating that each character in the first string should be replaced by the character in the same position in the second string. Got that In the case of our simple example, the code would look like the following: >>> from string import maketrans >>> table = maketrans('cs', 'kz')

The Title slide will be the rst thing to appear on the screen as you begin your talk, so it should intrigue the audience and set the visual tone of the presentation to come. In this instance, sketch a magnifying glass to illustrate searching, as indicated in the title, Searching for Solutions. As shown on the upper-left slide in Figure 7-3, sketch your organization s logo in the corner and perhaps add a note to use your company s colors on this slide.

print "R is within A to Z!" if ('A'..'Z').include ('r')

You can also use ranges as array indices to select multiple elements at the same time:
