Data Structures Laboratory: Write a Python program to store marks scored in subject “Fundamental of Data Structure” by N students in the class. Write functions to compute following

Problem Statement:

Write a Python program to store marks scored in subject “Fundamental of Data Structure” by N students in the class. Write functions to compute following:
a) The average score of class
b) Highest score and lowest score of class
c) Count of students who were absent for the test
d) Display mark with highest frequency
Note: Please Enter the capital A for absent students.


Code:

def absentStudents(marksList):
    absentCount=0
    for m in marksList:
        if(m=='A'):
            absentCount=absentCount+1
    print("Number of Absent Students",absentCount,"\n\n")

def averageScore(marksList):
    add=0
    for j in marksList:
        if(j!='A'):
         add=add+j
    print("The average score of class is",add/len(marksList),"\n\n")

def Highest_Lowest_Score(marksList):
    for k in range(0,len(marksList)):
        if(marksList[k]!='A'):
            for l in range(k,len(marksList)):
                if(marksList[l]!='A'):
                    if(marksList[k]>marksList[l]):
                        temp=marksList[k]
                        marksList[k]=marksList[l]
                        marksList[l]=temp
    
    print("Highest Score is",marksList[-1])
    print("Lowest Score is",marksList[0],"\n\n")

def highestFrequency(marksList):
    highestFrequencyNumber=0
    Frequency=0
    for n in range(0,len(marksList)):
        count=0
        for o in range(0,len(marksList)):
            if(marksList[n]==marksList[o]):
                count=count+1
        if(count>Frequency):
            Frequency=count
            highestFrequencyNumber=marksList[n]
    if(Frequency==1):
        print("No Numbers for Frequency.","\n\n")
    else:
        print(highestFrequencyNumber,"with Frequency",Frequency,"\n\n")
