Hurmatli o'quvchi! Ushbu masalalarni yechishda dasturlar bir oz original boHmasligi tabiiy, chunki men ham PYTHON dasturlash tliniendio'rganmoqdaman. Agarsizga ma'qul kelmasa tanqidiy fkr bildirmang dars davomida o'zgarishlarni o'quvchilarim yordamida dasturlarni ratsionallashtiib boramiz bundagi dasturlar asosan 9-sinf o'quvchisi o ^Khba darsgacha bilimga ega ekanligini hisobga olinglar. Bu qo'llanmani tayyortashda yaqindan yordam bergan @baliqchiio telegram kanali aZolariga ayniqsa Isomiddin Ismoilov, Sunnatullo Sultonmurodov, Dauletbay Kaipbayevlarga aloxida minnadorchilik bildiraman.67-68-dars mashqlarini o'zlarinng qoldiraman.
