What you want to do to get the list is shift the first letter of the string and append it to the back of the remaining sub-string through slicing:

def scrolling_text(string: str) -> list:
  new_list = []
  string = string.upper()
  for i in range(0, len(string)):
      if i != 0:
        string = string[1:] + string[:1]
      new_list.append(string)

  return new_list


print(scrolling_text('robot'))  # ["ROBOT", "OBOTR", "BOTRO", "OTROB", "TROBO"]
