The survey counter

A dictionary holds the number of students who gave each main reason in a survey. You will find the share of each reason and the reason that was given most.

The idea. The share of a reason is its count divided by the total of all the counts, times 100.

Your tasks.

1. Finish percent. It gives the per cent for one reason, to one decimal place.
2. Finish main_reason. It gives the reason with the largest count.
3. Finish shares. It gives a dictionary of the per cent for every reason.
