This tutorial introduces NoSQL using MonogDB and PyMongo under Python3.4. We will be using the find() command and comparison functions on the collection world which contains details of around 250 countries of the world:

FIND examples are available.

FIND name, continent, population FROM world

pp.pprint(list(
    db.world.find({},{
      "name":1,
      "continent":1,
      "population":1,
      "_id":0
    })
))

pp.pprint(list(db.world.find({},{"name":1,"continent":1,"population":1,"_id":0})))
