Note: Below are instructions for Task $1$ and Task $2$ of this homework. Please be sure to follow

these specific instructions. The grading rubric is based on these specific instructions. Your Python

script might be correct, but you receive no credit because you did not follow the instructions.

Task $1($of $2)$: Compute and Print Grades

Download students grades from the community site, Grades.txt$.$ The file has $6$ columns:

student Index number and the average RATs, CFUs, HWs$,$ Project and Exams grades for a set of

students. Each student has an Index number that is a whole number between $1$ and $300$ and their

final grade can be computed as a percentage based on the following formula:

Grade $\%=0\mathrm{.}05*$RAT $+0\mathrm{.}15*$CFU $+0\mathrm{.}15*$HW $+0\mathrm{.}20*$Project $+0\mathrm{.}45*$Exam

Their letter grade can then be assigned based on the following grade scale:

$90<=$ Grade $\%<=100$ A

$80<=$ Grade $\%<90$ B

$70<=$ Grade $\%<80$ C

$60<=$ Grade $\%<70$ D

$0<=$ Grade $\%<60$ F

Write a Python script called HW$3$p$2\_$Task$1\_$UCusername.py that will read in the Student Index

Number and the data from the Grades.txt file. Your script should then calculate the Grade

Percentage and determine the Letter grade based on the percentage for each student. The Student

Index Number, their grade percentage and letter grade should be stored to a new file

$($LetterGrade$.$txt$)$ for all students. A sample output for the first three students is shown below.

Note: it is not necessary for your columns to be nicely aligned. If you want to align columns,

you can control the width of each column in your $.$write command as follows: $\{0$:$15\}$ will make

item $0$ in the format list take up $15$ spaces. Similarly, $\{2$:$10\mathrm{.}2$f$\}$ will make item $2$ in the format

list take up $10$ spaces with two places behind the decimal point.
