use python, please!

Write a "grade calculation" program that does the following: 1. Ask the user for their name and store this value in a variable 2. Also ask the user for the name of a class and store this value in a variable as well 3. Ask the user for the weighting of tests in their class (i.e. tests are worth 60% of the total grade) 4. Ask the user for 3 test scores 5. Calculate the student's test average, and print it out to the user 6. Ask the user for the weighting of homework assignments in their class (.e. homework assignments are 40% of the total grade) 7. Ask the user for 3 homework assignment scores 8. Calculate the student's homework average, and print it out to the user 9. Calculate the student's final grade and display it to the user. Here's a sample running of the program: What is your name? Nikola What class are you in? Intro to Programming How much are tests worth in this class (i.e. 0.40 for 40%): 0.40 Enter test score #1: 90 Enter test score #2: 85 Enter test score #3: 97 Your test average is: 90.67 How much are homework assignments worth in this class (i.e. 0.60 for 60%): 0.60 Enter homework score #1: 100 Enter homework score #2: 90 Enter homework score #3: 80 Your homework average is: 90.0 Thanks, Nikola. Your final score in Intro to Programming is 90.27 Comment your source code and describe your code to someone who may be viewing it for the first time
