  • Не индентираш с 4 спейса, това може да ти коства всички точки, които би изкарал от задачата.
  • Измисли по-хубав начин за пазене на всички букви, списъкът не е добра идея.
  • След като напишеш останалите функции си помисли за по-елегеантен начин за проверка от всички вложени цикли.

Измисли по-хубав начин за пазене на всички букви, списъкът не е добра идея.

Измисли и по-добър начин да не вземаш под внимание разните символи. И най-вече, измисли по-адекватно име от string на твоята променлива. Това my_string дори не искам да го коментирам. Говорили сме 4 пъти за тези имена.
