How to access fields of a query
<p>I have a query that from this code </p>

<pre><code>cursor = db.MCAddrPortPairs.find({'Symbol' : symbol})[:1]
print str(json.dumps({'results': list(cursor)},
                        default = bson.json_util.default,
                        indent = 4))
</code></pre>

<p>returns the following doc:</p>

<pre><code>{
    "results": [
        {
            "MCPort": 345, 
            "Symbol": "EUR/USD", 
            "_id": {
                "$oid": "56fc34e961fed32064e656b0"
            }, 
            "MCAddr": "239.0.0.222"
        }
    ]
}
</code></pre>

<p>MCAddr is a string and MCPort is an int. How do I access the fields MCAddr and MCPort in python?</p>

<p><strong>EDIT 1</strong></p>

<p>If I say</p>

<pre><code>doc = db.MCAddrPortPairs.find({'Symbol' : symbol})[:1]

symbolMCIPAddrStr = doc["MCAddr"]
symbolMCPort = doc["MCPort"]
</code></pre>

<p>I get error:</p>

<pre><code>File "mc.py", line 44, in initializeMongo
    symbolMCIPAddrStr = doc["MCAddr"]
  File "/home/idf/anaconda/lib/python2.7/site-packages/pymongo/cursor.py", line 531, in __getitem__
    self.__check_okay_to_chain()
  File "/home/idf/anaconda/lib/python2.7/site-packages/pymongo/cursor.py", line 342, in __check_okay_to_chain
    raise InvalidOperation("cannot set options after executing query")
pymongo.errors.InvalidOperation: cannot set options after executing query
</code></pre>

<p><strong>EDIT 2</strong></p>

<p>If instead I say</p>

<pre><code>doc = db.MCAddrPortPairs.find_one({'Symbol' : symbol})[:1]


Traceback (most recent call last):
