Python, yahoo yql quote error

I have used the yql Console and have received an appropriate response. However, sending a python based query, I continue to have an error. First the console example:

select * from yahoo.finance.quotes where symbol in ("yahoo", "aapl")

I receive a results block that has the expected fields. The python example:

import requests
base_url = 'https://query.yahooapis.com/v1/public/yql?'
query = 'q=select * from yahoo.finance.quotes where symbol in ("YHOO", "AAPL")'
full_query=base_url + query
result = requests.get(full_query)
print(result.content)

With the following response:

b'\nNo definition found for Table yahoo.finance.quotes'

What am I missing? TIA, Clayton

What you are missing is the env part of the query:

import json
import urllib
from pprint import pprint

base_url = 'https://query.yahooapis.com/v1/public/yql?'
query = {
    'q': 'select * from yahoo.finance.quote where symbol in ("YHOO","AAPL")',
    'format': 'json',
    'env': 'store://datatables.org/alltableswithkeys'
}

url = base_url + urllib.urlencode(query)
response = urllib.urlopen(url)
data = response.read()
quote = json.loads(data)
pprint(quote)

Output:
