Student={ 'A';'B';'C'};
marks={100;100;100};
exam name={'D';'A';'C';'B'};
new marks={12;34;23;45};
i want to compare the exam name with the student and if it is the same I want the marks to be updated by the marks already in the new marks

is it possible to update the (marks) that have 100 instead of adding a new (mark1)
Simply use:
marks = new_marks(ia)
if the student name is not there I needed it to be 100 un changed
Do you think the above lines changing the value if student name is not exisitng?
