socket.gaierror in Google Data Python lib code - gdata

Question

I'm trying to execute this basic code from Getting Started with Google data:
`import gdata.docs.service
# Create a client class which will make HTTP requests with Google Docs server.
client = gdata.docs.service.DocsService()
# Authenticate using your Google Docs email address and password.
client.ClientLogin('jo#gmail.com', 'password')
# Query the server for an Atom feed containing a list of your documents.
documents_feed = client.GetDocumentListFeed()
# Loop through the feed and extract each document entry.
for document_entry in documents_feed.entry:
# Display the title of the document on the command line.
print document_entry.title.text`
The third line i.e. client.ClientLogin('myemail-id', 'my-password') is throwing an error:

Could you help me understand what this error is about and also how to work around this?
