Hello, I need help writing a python or dynamo script that will obtain the index in List 1 based on a specific range. The screenshot below hopefully will demonstrate what I am trying to achieve. Thank you! ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/8/48d11b442eda221b6b54a1ad6e0ef1821391d000.png) ---

Here’s a start but I can not figure out how to turn it into a loop to obtain all of the indices. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/4/04796065ae3b400c709004cdb28a4bb484e71044.png) [test.dyn](https://forum.dynamobim.com/uploads/short-url/gscvSZ6P41q1Guz1RpXgbTvGjwv.dyn) (22.4 KB) ---

Check all your possibilities first and _then_ check for the results that pass your condition. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/c/fc3bfddf437b3a0e3c558fbedb94873c6f500a65.png) ---
