How to get the values from MongoDB for user inputs

Hi I am creating collection(table) in mongodb like this;

DateBase name: Sample

Collection name: Sales

Id : xxxxxxxxxxxxx

India:1,23,456

Usa: 2,34,794

Asia:12,34,689

Now i want to get the values for user inputs dynamically

I am trying this code :

myclient = pymongo.MongoClient("mongodb://localhost:27017/")

mydb = myclient["sample"]

mycol = mydb["sales"]

loc = tracker.get_slot('location') // Inside the location values is India is stored in loc

counterNumber = mycol.count()

gettingTotalSize = mycol.find({}, {"_id": 0, "loc": 1})

for x in gettingTotalSize:

dispatcher.utter_message(str(x["loc"]))

return []
