I was working through the computer science track of code academy in the Hash Maps project (called Blossom). In order to successfully complete the project using the step by step instructions provided, I would have had to known about the iter method and yield functions which hadnt been covered previously.
The way LinkedLists were taught and the way it is used in the project is different.

Hello, @enginerdy, and welcome to the Codecademy Forums!
Link to project: Hash Maps: Blossom
Yes, the Hash Maps: Python lesson that precedes the Blossom project uses open addressing to handle collisions between keys. By contrast, the Blossom project uses separate chaining to handle collisions. While separate chaining is not presented in great depth prior to the Blossom project, it is introduced conceptually in the Hash Maps: Conceptual: Separate Chaining exercise.
When unfamiliar topics such as __iter__ and yield are encountered, a good place to look for reference information is the official Python web site. For example, see Data model: object.__iter__(self).
