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.

dh_pysupport

DH_PYSUPPORT(1) 						  python-support						   DH_PYSUPPORT(1)

NAME

       dh_pysupport - use the python-support framework to handle Python modules

SYNOPSIS

       dh_pysupport [debhelper options] [-V X.Y] [-X item [...]] [-n] [module dirs ...]

DESCRIPTION

       dh_pysupport is a debhelper program that will scan your package, detect public modules in /usr/lib/pythonX.Y/site-packages, and move them
       to the shared Python modules location. It will generate appropriate postinst/prerm scripts to byte-compile modules installed there for all
       available python versions.

       It will also look for private Python modules and will byte-compile them with the current Python version. You may have to list the
       directories containing private Python modules.

       If a file named debian/pyversions exists, it is used to determine the python versions with which the package can work.

       Appropriate dependencies on python-support, python and pythonX.Y are put in ${python:Depends}.  The ${python:Versions} and
       ${python:Provides} optional substitution variables are made available as well.

OPTIONS

       module dirs
	   If your package installs private python modules in non-standard directories, you can make dh_pysupport check those directories by
	   passing their names on the command line. By default, it will check /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE and
	   /usr/share/games/$PACKAGE

       -n, --noscripts
	   Do not modify postinst/postrm scripts.

       -d  This option is deprecated.

       -V X.Y
	   Force private modules to be bytecompiled with the specific X.Y python version, regardless of the default python version on the system.

       -X item, --exclude=item
	   Exclude files that contain "item" anywhere in their filename from being taken into account to generate the python dependency. It also
	   excludes them from byte-compilation. You may use this option multiple times to build up a list of things to exclude.
