Need Authentication/Login Example

I need a simple Python example NOT using the Developer access token. I want my user to enter their username and password or other persistent login method. I do not want them to have to refresh the developer token every 60 minutes. I then want to read a shared folder shared by another user across my company. I can read my own folder but when I try to access the shared folder using the SDK, I cannot. It says I am not an authorized user but I can access it through the web interface. So I do have access. I tried running the example.py in the demo directory on the BoxSDK GitHub but it poops out when trying to access localhost. I do not have a webserver setup. My understanding is it doesn't need to really exist but it's not working. I tried the other examples in the documentation but frankly the examples are terrible and the documentation poorly written.
