Ми мога само да изкоментирам, че като цяло генераторите ми работят, но с недостатъци.

Неможах да комбинирам всички условия на задачата. В името на това генератирите да продължават, за момента немога да модифицирам кода си, така че да разпознава повече от един генератори на азбука.

И втория е проблем са функции с повече от един аргумента. Немога да измисля достъпен начин за достъп и различаване на два аргумента при изградената до сега структура на кода ми.

Ще се радвам да чуя някакви насоки.
