Starter Code: Declare and initialize a $2-$D list with data in the given table

gradebook $=[["$Student Name","Math","Science","History"$],$

$["$John Doe",$85,90,78],$

$["$Jane Smith",$92,88,95],$

$["$Alice Johnson",$76,82,80],$

$["$Bob Brown",$89,94,85],$

$["$Charlie Green",$67,72,78],$

$["$Diana White",$94,91,88],$

$["$Evan Black",$81,85,79],$

$["$Fiona Blue",$75,70,84],$

$["$George Red",$88,92,90],$

$["$Holly Yellow",$79,84,86]]$ In the script, do the following:

a$)$ Print the table with proper alignment. Make sure to include the header for each column to show what

the column is about $($see sample output below$).$

b$)$ Calculate the average score over the $3$ courses for each student and print it as an extra column to the

right of the table. Keep $2$ digits after the decimal point for floating$-$point values.

c$)$ Based on the average score of each student, calculate their letter grade and print it as an extra column

to the right of the table.

Use the following grading scale for conversion:

Average Score Letter Grade

$>=90$ and $<=100$ A

$>=80$ and $<90$ B

$>=70$ and $<80$ C

$>=60$ and $<70$ D

Below $60$ F

d$)$ For each course, calculate the average score of the entire class, and print them as an extra row at the

bottom of the table. Keep $2$ digits after the decimal point for floating$-$point values.

$4.$ Submit your completed CS$1300\_$A$5.$py file on Canvas.

Note that:

$-$ You can do everything in the main program, or write your own functions if necessary $($not required$),$

but you must use the given starter code to begin.

$-$ You may use any of the Python class methods as well as other built$-$in functions, but NOT any

internal or external packages $($i$.$e$.$ no import statement is allowed in your script$).$

$-$ Please include comments throughout the body of your program to explain what the code is doing.

Furthermore, if you write functions, please include documentation for each function using docstrings.

$-$ You are expected to use repetition statements whenever possible. For instance, if you manually add

up the values in a column using a large addition expression, it will be considered hardcoding. You can

refer to Ch$\mathrm{.}7$ of the class notes regarding how to iterate over a multi$-$dimensional list.
