Complete the following task for this assignment.

Write a program that calculates category averages and overall course average for CS $170.$

The grade categories are lab, programming assignments, exam$1,$ exam$2,$ and final exam.$($Labs are worth $10\%,$ programming assignments are worth $20\%,$ exam $1$ is worth $68\%,$

exam $2$ is worth $25\%,$ and the final exam is worth $25\%).$

Ex$.$ If lab avg $=70,$ pa avg $=91,$ exam$1$ avg $=68,$ exam$2$ avg $=95,$ final exam avg $=70$:

$=(70\backslash$times $0\mathrm{.}1)+(91\backslash$times $0\mathrm{.}2)+(68\backslash$times $0\mathrm{.}2)+(95\backslash$times $0\mathrm{.}25)+(70\backslash$times $0\mathrm{.}25)=80\%$

Your program must display the grades and averages for each category. Your program will

also calculate and display the overall exam average and course grade $($see sample run$).$

Input: This program uses separate input files for each grade category. All input files are

of unknown length and end with a sentinel value of $-1$:

$$ LabGrades.py: contains lab assignment grades.

$$ PaGrades.py: contains programming assignment grades.

$$ Exam$1$Grades.py: contains exam $1$ grades.

$$ Exam$2$Grades.py: contains exam $2$ grades.

$$ FinalExamGrades.py: contains final exam grade.

In your code, you will read the data from each input file and store it in its list. Therefore,

you will have $5$ separate lists to maintain.

Functions: Your program must include user$-$defined functions for the following tasks:

$$ def GetMaxPts$()$

This function is used to prompt the user to enter the total number of points possible in

each category. These values are used in computing the category averages. The

function returns the maximum point values for labs, programming assignments, exam

$1,$ exam $2,$ and the final exam $(5$ values$).$ The function has no input parameters.

$$ def AddNumsToList $($listName$,$ filename$)$

This function opens the input file specified by filename, reads the data, and appends

it to the list listName. The sentinel value indicating the end of the file is $-1$ for each

input file. The function returns the list containing the data to main$().$

$$ def FindSimpleAvg $($listName$,$ totalPts$)$

This function calculates the average of the grade category. It accepts as parameters

the list of grades $($listName$)$ and the total number of possible points for that category

$($totalPts$).$ The function returns the calculated average to main$().$ This function does

not print any results.

$$ def PrintGrades $($category$,$ listName, average$)$

This function prints the grades and averages for a single category. You will call this

function each time you want to display a set of grades and an average. The input

parameters are category $($a string $$ either $$Labs$,$PAs$,$Exam$1,$Exam$2,$ or

$$Final Exam$$ as appropriate$),$ listName $($the list of grades to be printed$),$ and average

$($the average that was calculated for the category$).$

$$ def main$()$:

The main function of your program will call the above user$-$defined functions. Unlike

other assignments with file input, there is no reading from the file loop in main$().$

This loop is in the AddNumstoList function. Since there is no user$-$defined function

for calculating the overall exam average and weighted course average, you can

include those calculations and printing in main$().$

NOTE: All code should be inside of a function. The only thing outside of a function $($i$.$e$.,$

aligned all the way to the left$)$ is the call to invoke main$().$

Output.

All averages should be displayed in two decimal places
