Get all documents of a collection using Pymongo

Here is the sample code which works fine when you run from command prompt.

from pymongo import MongoClient

if __name__ == '__main__':
    client = MongoClient("localhost", 27017, maxPoolSize=50)
    db = client.localhost
    collection = db['chain']
    cursor = collection.find({})
    for document in cursor:
          print(document)

Please check the collection name.
