Challenge: Updating Dictionary

Uppgift

Swipe to start coding

You are given the dictionary students_grades, where the student's name is the key, and their exam grade is the value.

Some students came to take the exam because they were previously not allowed, so they need to be added to the dictionary. Also, one student improved their poor grade, so their grade in the dictionary needs to be updated.

Add the student John with a grade of 75.
Add the student Alice with a grade of 92.
Change the grade of the student Peter from 54 to 84.
