You can get a specific collection in a project by calling client.collections().get(name). Getting a single collection is as easy as: 
collection = client.collections().get("books")
The get() function takes the name of a collection and returns a single Collection object. 
print(f"Collection name: {collection.name}")
print(f"Organization ID: {collection.org_id}")
print(f"Project ID: {collection.project_id}")
print(f"Region: {collection.region}")
print(f"Schema: {collection.schema}")
