Homework Assignment 5 Instructions: Class name must be: HW5_yourName For example: Michael will name the python file of homework assignment 5 as HW5_Michael.py Grading Rubric: Code running and as per the required conditions and giving expected output = 10 points File named as per instructions = 1 point Comments in code = 4 points Problem: Average calculation of test scores using a Dictionary Write a program that reads a text file named Asg5_data.txt and stores the name of the student as the key of the dictionary element. The scores of each student will be stored in a list and the list will be the value of the key of Dictionary element. The dictionary with key-value pair is shown in Expected Output. The program should display average (average of 2 tests) for each student. Expected Output: Dictionary of student and their test scores is: {'michael': [25, 23], 'adelle': [26, 28], 'james': [24, 26], 'anders': [23, 29]} Dictionary of student and their average test scores is: {'michael': 24.0, 'adelle': 27.0, 'james': 25.0, 'anders': 26.0}
