Using a dictionary is similar to using user name/ password for logging into any site I understand?
Thank you for reaching out.
Though a simplified comparison, using a dictionary in Python to manage user names and passwords can be somewhat analogous to the process of logging into a website. In real-world applications, however, storing passwords as plain text (as done in a simple dictionary) is not secure; passwords should be stored using secure hashing. Additionally, for a large number of users, a dictionary in memory isn't practical; real applications use databases. Lastly, real login systems include additional functionalities like handling password resets, email verification, etc., which are not inherently part of a simple dictionary usage.
Enjoy the course!
