What do the PyMongo docs mean by "sub-collection"?

This page in the documentation says you can access a collection using c[name] or c.name, where c is a Collection, but what exactly does a sub-collection mean? I couldn't find any use of the term in the mongodb docs.

What I'm assuming, is that it gets the value of each document at key name, wihtin the collection, and represents that as its own collection. Is this the case?

A subcollection is just a naming convention of using . in a collection name as a way to organize your collection names.

So with the following code:

client = pymongo.MongoClient()
db = client['mydb']
coll = db['test']
subcoll = coll['subtest']

subcoll is a collection with a name of test.subtest. There's no defined relationship between test and test.subtest, it's just naming.
