• The while loop should in dice_roller should be a for loop (for roll in range(nb_dice):)
  
• write_result is inefficient. You are recreating that string every time through the loop. Create the string once before the loop, and write the line without a function.
  
• I would remove write_total and just put that one line of code in the loop in dice_roller. It's just adding a function call to every iteration of the loop.
  
• setup_list can be replaced with [0] * nb_results. I would actually make it one longer. Then you can just add one to result_list[result] on line 13. That saves another subtraction each loop iteration.
  
• Your variable and function names are nice and clear. The next step is to start commenting your code, and adding docstrings to your functions.
