Question

Python program:

Write a program that reads a text file named test_scores.txt to read the name of the student and his/her scores for 3 tests. The program should display class average for first test (average of scores of test 1) and average (average of 3 tests) for each student.
Expected Output:
['John', '25', '26', '27']
['Michael', '24', '28', '29']
['Adelle', '23', '24', '20']
[['John', '25', '26', '27'], ['Michael', '24', '28', '29'], ['Adelle', '23', '24', '20']]
Class average for test 1 is: 24.0
Average for student John is 26.00
Average for student Michael is 27.00
Average for student Adelle is 22.33

# function to read file to
# get marks of student
def test_score(filename):
    content = []
    avg=0
    name=[]
    average=[]
    count=0
    test1=0

    # open file
    f=open(filename,"r")

    # read each lines
    for line in f:
        count=count+1
        # content of line
        content=line
        # convert string to integers and stores in array 
        numbers = [int(word) for word in content.split() if word.isdigit()]

        # get the test1 data for each student and add to test1
        test1=test1+numbers[0]
        
        # find current student average score
        avg=sum(numbers)/len(numbers)

        # get the name of each student
        # and store inside list
        data= content.split()
        name.append(data[0])

        # store the average of three subjects
        average.append(avg)

    # display the result
    print("Class average for test 1 is: ",test1/count)
    for i in range(count):
        print("Average for student ",name[i], " is ","%0.2f" % round(average[i],2))
        
        
# main function
def main():
    # call function tet_score to
    # get the targeted result
    test_score("test_scores.txt")
