test$\_$scores$[$k$]$ returns the value of the key$-$value pair with k as the key.

del test$\_$scores$[$k$]$ deletes the entry test$\_$scores$[$k$].$

Ex: test$\_$scores contains 'Fay': $67$ and 'Ana': $40.$ If input is Ana, then test$\_$scores$[$key$\_$name$]$ accesses and outputs the value $40.$ Then, 'Ana': $40$ is deleted from test$\_$scores. The remaining pair in test$\_$scores is 'Fay': $67.$

Not all tests passed.
