  Hi Olafia,

  I suggest following:

  1) Create a list with the numbers from 0 to 9
  2) Create two placeholder variables to store the two preceding values and assign an arbitrary value to them.
  3) use random.choice to pull a random number from your list repeatedly in a whileloop and add these values to a new list, that contains all stimuli of your stream, unless they match any of the placeholders and update your placeholder variables.
  4) Et voila!

  Here everything in (almost) python code:

  import random
  numbers = list(range(9))
  target_list = []
  prev1 = 10
  prev2 = 10
  
  while len(target_list) < targeted_length:
      no = random.choice(numbers)
      if no not in [prev1,prev2]:
          target_list.append(no)
          prev2 = prev1
          prev1 = no
  

  Does this make sense?

  Eduard
