Retrieving documents using .find()
One common way of retrieving documents from a MongoDB collection is .find(). When called on a collection, it will return a cursor object pointing to all records or all records that match a specified filter query. Using list() you can actually fetch the documents, and go from a cursor object to a Python list.
