title: Raspberry pi 'Response IndentationError'
body: <p>I have been looking at a tutorial on how to send sms texts through the rasp pi. Here is the code that I have and I'm not sure why I have an error.</p>

  #  
  #----------------------------------- 
  
  # Import required libraries 
  import urllib # URL functions 
  import urllib2 # URL functions 
  
  # Define your message 
  message = 'Test message sent from my Raspberry Pi' 
  
  # Set your username and sender name. 
  # Sender name must alphanumeric and 
  # between 3 and 11 characters in length. 
  username = 'jonfdom1@aol.com' 
  sender = 'Jonny.D' 
  
  # Your unique hash is available from the docs page 
  # https://control.txtlocal.co.uk/docs/ 
  hash = '8fe5dae7bafdbbfb00c7aebcfb24e005b5cb7be8' 
  
  # Set the phone number you wish to send 
  # message to. 
  # The first 2 digits are the country code. 
  # 44 is the country code for the UK 
  # Multiple numbers can be specified if required 
  # e.g. numbers = ('447xxx123456','447xxx654321') 
  numbers = ('447xxxxxx260') 
  
  # Set flag to 1 to simulate sending 
  # This saves your credits while you are 
  # testing your code. 
  # To send real message set this flag to 0 
  test_flag = 1 
  
  #----------------------------------- 
  # No need to edit anything below this line 
  #----------------------------------- 
  
  values = {'test' : test_flag, 
  'uname' : username, 
  'hash' : hash, 
  'message' : message, 
  'from' : sender, 
  'selectednums' : numbers } 
  
  url = 'http://www.txtlocal.com/sendsmspost.php' 
  
  postdata = urllib.urlencode(values) 
  req = urllib2.Request(url, postdata) 
  
  print 'Attempt to send SMS ...' 
  
  try: 
  response = urllib2.urlopen(req) 
  response_url = response.geturl() 
  if response_url==url: 
  print 'SMS sent!' 
  except urllib2.URLError, e: 
  print 'Send failed!' 
  print e.reason
  </code></pre>
  
  <p>And here is the error message I have popping up on the terminal</p>
  
  <pre><code> File "send_sms.py", line 331
      response = urllib2.urlopen(req) 
             ^
  IndentationError: expected an indented block
