Бих използвал ord('a'), за да взема тази стойност динамичо. Не че някой ще променя ASCII таблицата, но в други подобни случаи би било полезно.

Иаползваш доста литерали. Или използвай ord(), за да ги вземеш динамично, или ги деифнирай като константи. Иначе са просто магически стойности в кода ти и не е ясно откъде идват.

Съветвам те да изтестваш граничните стойности. Според мен имаш пропуски с тях.
А защо не използваш директно
len(nums)? Хем спестяваш променлива, хем е по-кратко.
