Algo que eu descobri durante um teste....

from pymongo import MongoClient


client = MongoClient()

db = client.test_database

expected_doc = {
    "name": "alexandre",
    "lang": "python3",
    "etc": "potato"
}

db["my_new_collection"].insert(doc_or_docs=expected_doc)

# _id -> False to return only the original doc value
try:
    assert db["my_new_collection"].find_one(expected_doc, {"_id": False}).keys() == expected_doc.keys()
    assert db["my_new_collection"].find_one(expected_doc, {"_id": False}).values() == expected_doc.values()
except AssertionError:
    print("Fail! Now your dict items is: ")
    print(expected_doc.items())

É...vai cair no except. Motivo:

Uma seleção um pouco mais especifica:
