Counting all words that start with a capital letter in a string using python dictionary

Hi,

I have written the following python snippet to store the capital letter starting words into a dictionary as key and no of its appearances as a value in this dictionary against the key.

Code:

#!/usr/bin/env python
import sys
import re
hash = {} # initialize an empty dictinonary
for line in sys.stdin.readlines():
    for word in line.strip().split(): # removing newline char at the end of the line
        #l = re.search("\b[A-Z]\S+", word)
        if word[0].isupper():
            if word in hash:
                hash[word] += 1
            else:
                hash[word] = 1
for word, cnt in hash.iteritems(): # iterating over the dictionary items
    sys.stdout.write("%d %s\n" % (cnt, word))

In the above code, I am using the array index to check for the uppercase. But when I tried to re-code it using the regular expression as:

Code:

l = re.search("\b[A-Z]\S+", word)

that is not fetching me the anticipated output. Expecting your help in this regard.

CREATE TEXT SEARCH 
DICTIONARY(7)			  PostgreSQL 9.2.7 Documentation			  CREATE TEXT SEARCH DICTIONARY(7)

NAME

       CREATE_TEXT_SEARCH_DICTIONARY - define a new text search dictionary

SYNOPSIS

       CREATE TEXT SEARCH DICTIONARY name (
	   TEMPLATE = template
	   [, option = value [, ... ]]
       )

DESCRIPTION

       CREATE TEXT SEARCH DICTIONARY creates a new text search dictionary. A text search dictionary specifies a way of recognizing interesting or
       uninteresting words for searching. A dictionary depends on a text search template, which specifies the functions that actually perform the
       work. Typically the dictionary provides some options that control the detailed behavior of the template's functions.

       If a schema name is given then the text search dictionary is created in the specified schema. Otherwise it is created in the current
       schema.

       The user who defines a text search dictionary becomes its owner.

       Refer to Chapter 12, Full Text Search, in the documentation for further information.

PARAMETERS

       name
	   The name of the text search dictionary to be created. The name can be schema-qualified.

       template
	   The name of the text search template that will define the basic behavior of this dictionary.

       option
	   The name of a template-specific option to be set for this dictionary.

       value
	   The value to use for a template-specific option. If the value is not a simple identifier or number, it must be quoted (but you can
	   always quote it, if you wish).

       The options can appear in any order.

EXAMPLES

       The following example command creates a Snowball-based dictionary with a nonstandard list of stop words.

	   CREATE TEXT SEARCH DICTIONARY my_russian (
	       template = snowball,
	       language = russian,
	       stopwords = myrussian
	   );

COMPATIBILITY

       There is no CREATE TEXT SEARCH DICTIONARY statement in the SQL standard.
