Sort the Result
 Use the sort() method to sort the result in ascending or descending order.
The sort() method takes one parameter for "fieldname" and one parameter for "direction" (ascending is the default direction).
Sort the result alphabetically by name:
import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
mydoc = mycol.find().sort("name")
for x in mydoc:
  print(x)

Sort Descending
 Use the value -1 as the second parameter to sort descending.
sort("name", 1) #ascending
sort("name", -1) #descending
Sort the result reverse alphabetically by name:
import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
mydoc = mycol.find().sort("name", -1)
for x in mydoc:
  print(x)
