I have already completed the create and read below. I need help with the update and delete part. I have attached my completed work below as well. As well as the instructions for the assignment

Next, you must develop a Python module in a PY file, using object-oriented programming methodology, to enable CRUD functionality for the database. To support code reusability, your Python code needs to be importable as a module by other Python scripts. Develop a CRUD class that, when instantiated, provides the following functionality:

• A Create method that inserts a document into a specified MongoDB database and collection
  • Input -> argument to function will be a set of key/value pairs in the data type acceptable to the MongoDB driver insert API call.
  • Return -> True if successful insert, else False.
• A Read method that queries for document(s) from a specified MongoDB database and specified collection
  • Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call.
  • Return -> result in cursor if successful, else MongoDB returned error message.
• An Update method that queries for and changes document(s) from a specified MongoDB database and specified collection
  • Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call. Last argument to function will be a set of key/value pairs in the data type acceptable to the MongoDB driver insert API call.
  • Return -> result in JSON format if successful, else MongoDB returned error message.
• A Delete method that queries for and removes document(s) from a specified MongoDB database and specified collection
  • Input -> arguments to function should be the key/value lookup pair to use with the MongoDB driver find API call.
  • Return -> result in JSON format if successful, else MongoDB returned error message.
