You have access to a database of `student_scores` in the format of a dictionary. The **keys** in `student_scores` are the **names** of the students and the **values** are their exam **scores**.  Write a program that **converts their scores to grades**. By the end of your program, you should have a new dictionary called `student_grades` that should contain student **names** for **keys** and their **grades** for **values**. T**he final version** of the `student_grades` dictionary will be checked. student_scores = { "Harry": 81, "Ron": 78, "Hermione": 99, "Draco": 74, "Neville": 62, } #TODO-1: Create an empty dictionary called student_grades. student_grades = {} #TODO-2: Write your code below to add the grades to student_grades.👇 for student in student_scores: score = student_scores[student] if score > 90: student_grades[student] = "Outstanding" elif 80 < score < 91: student_grades[student] = ...
