Can't always retrieve data from Google

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call "get_weather_from_google" multiple times.

Sometimes you can retrieve values and sometimes you end up with "Unsupported 
API". Since it is generally working, Google seems to have servers, that do not 
answer to pywapi any more.

Probably it has something to do with automated queries 
(http://support.google.com/websearch/bin/answer.py?hl=en&answer=86640&rd=1).

I have a script that retrieves weather data every five minutes, so you might be 
right, nevertheless this problem didn't occur in the last five or six months 
and I have switched to Yahoo Weather instead, which is working fine. 

So if no one else is running into that problem with the Google API, then my IP 
might have gotten onto a blacklist that prohibits such frequent queries.

Google stopped his weather api ... no longer works.

Thanks for the notice. I hope that Yahoo won't follow any time soon. :-)

Google has discontinued their Weather API as of August 2012, this cannot be 
fixed.
