Може да греша, но логиката, която едновременно повишава i и понижава numbers_length, ще пропусне някои символи. Виждам, че си взела мерки за промяната на тези променливи при определени условия, но все пак имам предчуствие, че лоигаката се чупи в конкретни случаи. Съветвам те да изтестваш добре, за да си сигурна, че не съм прав.

Дори да работи правилно, този похват е доста "чуплив" и труден за разбиране от читателя, така че те съветвам да се опиташ да инкрементираш само една променлива.

Да, горният коментар е нужен, за да знаеш за други проекти, но като цяло и този цикъл е излишне. Можеш просто да вземеш елемент от dict по ключ: alphabet['letter'] или alphabet.get('letter'), застраховайки се с отделна проверка, че резултатът не е None или exception, в случай на нужда.
