Hi Evan. You are close but have a few issues:

  1. Instead of printing the numbers you want to return them so replace print with return
  2. You have wrong slashes instead of d/{3}, you want d\{3}
  3. And lastly you need to pass the number variable to the findall method. so at the end where you have a comma add ,number)
......findall(.........,number )

Hope this helps and if you are still stuck post back to the community
