Combining Two Lists While Repeating Items From the First List

I apologize if this is a very simple question. Please bear with me as I am still fairly new to Dynamo. Can someone please guide me on how to combine two lists into one list that looks like the text in the attached image? I have tried searching topics related to lists and i have watched many videos, but I cannot seem to find the correct steps to accomplish this seemingly simple task. Thank you.

The first thing you have to understand is that not all list level permutations are possible within a defined list structure. Node inputs tend to require specific structures. Even though they can “automatically” adapt to other structures in many cases, there is an underlying requirement in how inputs should align.

In many cases it’s necessary to adjust one or more inputs (usually by repeating values) to align with the intended structure.

You can also use replication guides within code blocks to further specify how list structure should be handled when iterating multiple inputs.

Thank you very much for the detailed explanation and for taking the time to show me a couple of methods of how to accomplish this. It works great now!
