REST APIs with Flask and Python - Solution to Coding Exercise: Dictionaries and Students

This video tutorial guides students through a coding exercise in Python, focusing on creating and modifying dictionary variables and implementing a function to calculate the average grade for a class. The tutorial is divided into three parts: creating a dictionary with specific keys and values, modifying a variable to access dictionary keys, and implementing a function to calculate the average grade. The instructor provides detailed explanations and examples to help students understand the concepts and apply them in their coding exercises.

Describe how to calculate the total and count of grades in the student list.

What is the significance of using total += sum(student grades) in the code?

Why is it important to assign the count variable back after calculating its value?
