Alarm clock that interacted with google calendar API - python-2.7

Question

I am looking for some help on an alarm clock that interacted with google calendar.
I have some problem with the code now where is not pulling down the events.
here is the errore i get now:
INFO:main:Polling calendar for events...
INFO:googleapiclient.discovery:URL being requested: GET https://www.googleapis.com/calendar/v3/calendars/primary/events?alt=json&singleEvents=true
INFO:main:Polling calendar for events...
INFO:googleapiclient.discovery:URL being requested: GET https://www.googleapis.com/calendar/v3/calendars/primary/events?alt=json&singleEvents=true
Process finished with exit code -1

I have changed the code and got it to work using this code from Matt http://mattdyson.org/projects/alarmpi/#comment-20249
This is the code that I have changed. It is not pretty yet just works for now
