+Algo que eu descobri durante um teste....
+```python
+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:
