You already have learned how to use a $2$D list. Today we utilize the $2$D list to solve the problem. You are given an input file $($input$.$csv Download input.csv$)$ where a list of students and their grades are listed. Your task is to read the file content, populate the $2$D list, and finally do some calculations $($min$,$ max, median, and average$)$ for each course. You CAN NOT use any built$-$in functions, like min, max, sort, etc. as well as csv module in this assignment. However, for the median, you can ONLY use a built$-$in function from the statistics module. After calculating these, you need to store them in an output file. A sample output file $($output$.$csv Download output.csv$)$ is given for the corresponding input file. I may use different input files which will generate different output files. Before submitting your in$-$class, make sure your code runs correctly and generates the specified output file. You may use a different input file for your test case.

You are only supposed to submit the $.$py file named as $\text{'}\{$firstname$\}\_\{$lastname$\}\_2$d$\_$list.py$\text{'}$ before the deadline.

Rubrics

a$)$ Use the coding format given in the class which should contain a main$(),$ docstring, and several utility functions based on your need. $(2)$

b$)$ Populate a $2$D list from the input file $(3)$

c$)$ Calculation with several utility functions $(3)$

d$)$ Store the results in the output file $(1)$
