python - Is it possible to get the Standard deviation of a field in pymongo? -

-

i have query:

cursor = collection.aggregate(   [       {"$match": {"name":{"$in":namelist}}},       {           "$group":               {                   "_id":"$name",                   "average": {"$avg":"$price"},                                                                                                 "max": {"$max":"$price"},                   "min": {"$min":"$price"},                   "count": {"$sum": 1},              }      }   ]   )

is possible standard deviation in similar fashion?
