Command line English-Turkish dictionary

I've been reading Python tutorials since I accidentally see the Zen of Python. I think I read enough. Now its time to get hands dirty. The best way to learn a language is to write code in that language. I have implemented a command line dictionary that fetches the Turkish definition of a given English word from the site Sesli Sözlük. The python script below uses BeautifulSoup HTML/XML parser for screen-scraping.
This is sozluk.py. It reads program arguments and constructs a URL. After fetching URL content BeatifulSoup library is used to get desired parts of the HTML page. Finally results are printed to the stdout.

from BeautifulSoup import BeautifulSoup
import urllib2
import sys
import string


def getDefinitions(keyword):
 
 url = 'http://www.seslisozluk.com/?word='+keyword
 c=urllib2.urlopen(url)
 soup=BeautifulSoup(c.read())
 results = soup.findAll(attrs={"class" : "dict_result"})[0].contents[1].contents 
 definitions = [results[x] for x in range(len(results)) if ((x+2)%3)==0]
 return [definition.replace(' ', '') for definition in definitions]


if __name__ == '__main__':
 if len(sys.argv)<=1:
  print 'missing keyword.'
 else:
  keyword =' '.join(sys.argv[1:]) 
  try:   
   definitions = getDefinitions(keyword)
   for i in definitions:
    print i
  except:
   print "Failed to get definition of ",keyword

This is sozluk.sh. It is used to call Python Interpreter and execute sozluk.py.

#!/bin/bash
#sozluk.py is in this folder.
cd /home/ilkinulas/PITON/workspace
python sozluk.py $1
