findOne is a db collection's method in MongoDB. find_one is a Python API wrapper around find. With PyMongo API's find_one you can send more parameters to control the output.\n\nfindOne has filter and projection parameters whereas find_one has more parameters: filter, projection, skip, limit etc.\n\nIf you using PyMongo, focusing on find() and find_one() will be more helpful than focusing on pure Mongo's findOne.",
