  • letter_list не е list, това е объркващо
  • не трябва типа на обекта да присъства в името на променливите: words_list, letter_list, symbol_dict

  • word2 не е добър избор за име на променлива

      if not type(key) in result:
      result[type(key)] = {key: dictionary[key]}
  else:
      result[type(key)][key] = dictionary[key]

Разгледай за defaultdict.

return (sorted(list(word1)) == sorted(list(word2))) - скобите в израза са илишни
