Hi :)

I was reading the docs looking for an example to handle exceptions from when request.execute() goes wrong e.g. a 403 due to
Exceeding qouta limits.

I would like for the docs to be updated with a try: and except: like this

    try:
        response = request.execute()
    except HttpError as e:
        logger.error('Error response status code %d, reason %s:', e.resp.status, e.content)
        return {'error': 403, 'body' : 'YouTube API Data v3 qouta limit exceeded'}

or something else in the except block

If you're happy with this I'd like to contribute this as a first timer to open source?
