The second statistic you wanted to get relating to characters was a character total excluding whitespace. If you can remember back to 3, strings have a gsub method that performs a global substitution (like a search and replace) upon the string. For example:

Dictionaries are written like this: phonebook = {'Alice': '2341', 'Beth': '9102', 'Cecil': '3258'} Dictionaries consist of pairs (called items) of keys and their corresponding values. In the preceding example, the names are the keys and the telephone numbers are the values. Each key is separated from its value by a colon (:), the items are separated by commas, and the whole thing is enclosed in curly braces. An empty dictionary (without any items) is written with just two curly braces, like this: {}.

"this is a test".gsub(/t/, 'X')

You can use gsub to eradicate the spaces from your text string in the same way, and then use the length method to get the length of the newly de-spacified text. Add the following code to analyzer.rb:

FIGURE 7-5 Four ways to sketch the Role slide: using the Setting slide s photograph and updating the headline, using the Setting slide s chart and adding a magnifying glass, showing only the headline and the magnifying glass, and hiding the headline.

total_characters_nospaces = text.gsub(/\s+/, '').length puts "#{total_characters_nospaces} characters excluding spaces"

Note Keys are unique within a dictionary (and any other kind of mapping), while values may not be.

If you run analyzer.rb in its current state against the Oliver Twist text, the results should be similar to the following:

In a similar way, if you sketched a chart on the Setting slide, as shown on the lower-left slide in Figure 7-4, use it again on the Role slide. Sketch a small magnifying glass over the chart to illustrate the searching theme from the headline, as shown on the upper-right slide in Figure 7-5. Carrying over the same graphical element from the preceding slide helps to tell the story visually across the two storyboard frames. Your verbal explanation will keep the story owing too, as you transition between the two slides by saying something like, Although we all can agree that the returns are declining, we can also agree that you want to do something about it. Advance to the Role slide, and say, Like everyone else, you ve been searching for the next thing to do.

121 lines 6165 characters 5055 characters (excluding spaces)

The regular expression looks odd here, but the full stop, question mark, and exclamation mark are clearly visible. Let s look at the regular expression directly:

Try something a little different by sketching only a magnifying glass on the Role slide, as shown on the lower-left slide in Figure 7-5. This turns the slide into a visual prompt in which a photograph alone prompts you to unlock your natural voice. If you keep the photograph simple, the audience members will use their imagination and see themselves in the role and in the setting you verbally and visually describe.

You can use the dict function to construct dictionaries from other mappings (for example, other dictionaries) or from sequences of (key, value) pairs: >>> items = [('name', 'Gumby'), ('age', 42)] >>> d = dict(items) >>> d {'age': 42, 'name': 'Gumby'} >>> d['name'] 'Gumby' It can also be used with keyword arguments, as follows: >>> d = dict(name='Gumby', age=42) >>> d {'age': 42, 'name': 'Gumby'} Although this is probably the most useful application of dict, you can also use it with a mapping argument to create a dictionary with the same items as the mapping. (If used without any arguments, it returns a new empty dictionary, just like other similar functions such as list, tuple, or str.) If the other mapping is a dictionary (which is, after all, the only built-in mapping type), you can use the dictionary method copy instead, as described later.

The forward slashes at the start and the end are the usual delimiters for a regular expression, so those can be ignored. The first section is \. and this represents a full stop.
