| 2 Hurmatli o`quvchi! Ushbu masalalarni yechishda dasturlar bir oz original bo`lmasligi tabiiy, chunki men ham PYTHON dasturlash tilini endi o`rganmoqdaman. Agar sizga ma’qul kelmasa tanqidiy fikr bildirmang dars davomida o`zgarishlarni o`quvchilarim yordamida dasturlarni ratsionallashtirib boramiz bundagi dasturlar asosan 9-sinf o`quvchisi o`sha darsgacha bilimga ega ekanligini hisobga olinglar.
