sort()
is a cursor method that orders the results of a query.
The aggregation framework provides the $sort
operator, and map_reduce
takes sort as a parameter that is applied to the input documents.
The syntax for sort()
is sort(<field>:<value>)
where 1 indicates ascending and -1 indicates descending.
The order in which fields are specified dictates which fields are sorted first.
Sort all the documents in world by population descending, then name ascending.
for x in list(db.world.find().sort({"population":-1,"name":1})): print(x)
