A quick class I put together to access Google BigQuery data via query through Python.

1. Go to the Google APIs console to create a new project.
2. Services > BigQuery > status ON
3. API Access > "Create another client ID...". Choose "Service account" and click Create.
4. Download your private keyfile.
5. Note down your service account's email address and project number (Overview > Project number).

Some example usage with Google ngrams:

import easybigquery
API = GoogleAPIFromServiceAccount(projectNumber, serviceEmail, pathToKeyfile)
bq = GoogleBigQuery(API)

def rawNgramData(word):
	query = "SELECT ngram, cell.volume_fraction FROM publicdata:samples.trigrams WHERE ngram CONTAINS '%s' GROUP BY ngram, cell.volume_fraction;" % word
	return bq.query(query)

print rawNgramData("robot")
