eval-а спокойно ще ти донесе нула точки за решението, без значение колко теста минава.
Би ли ми казал, защо избора на eval() е лош. Питам за да разбера смисала а не като критика, че не ми даваш да го ползвам. Видях ,че може да заменя eval s globals и да ми върши същата работа, това ли имаше предвид ?
