title: How to create application with users
body: <p>I'm creating a program that will allow groups of people (e.g flatmates) to manage their funds. I want people to be able to download the app and have different users that will interact with each other.
  I can't seem to find a platform that will help me combine the classes and class methods (python) with an actual database/user management program.
  can anyone help with directions on what I should look for? </p>
  
  <p>This is a program written in Python. I wanted it to be object oriented when the users and the groups are the classes. I'm flexible with this idea.
  currently I'm using vscode with pyMongo as a database but can't understand how to do the user identification and interactions there.</p>
