Question:

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

Code:

# Function for count of student absent for test

def absentSC(listOfStudent, numberOfStudent):
   count = 0
   for i in range(numberOfStudent):
       if listOfStudent[i] == 0:
           count += 1
   return count


# Function for Maximum-------------------------------------------->>

def maxMarks(listOfStudent, numberOfStudent):
   max = 0
   for i in range(numberOfStudent):
       if max < listOfStudent[i]:
           max = listOfStudent[i]

   return max


# Function to calculate largest marks frequency

def largestMFreq(numberOfStudent, listOfStudent):
   count = 0
   check = maxMarks(listOfStudent, numberOfStudent)

   for i in range(numberOfStudent):
       if check == listOfStudent[i]:
           count += 1
   return count


# Function to calculate minimum marks frequency

def minMFreq(numberOfStudent, listOfStudent):
   count = 0
   check = minMarks(listOfStudent, numberOfStudent)

   for i in range(numberOfStudent):
       if check == listOfStudent[i]:
           count += 1
   return count


# Function for Minimum------------------------------------------->>>

def minMarks(listOfStudent, numberOfStudent):
   min = listOfStudent[0]
   for i in range(numberOfStudent):
       if min > listOfStudent[i]:
           min = listOfStudent[i]

   return min


# Function for Average--------------------------------->>>

def averageOfMarks(listOfStudent, numberOfStudent):
   sumInitialize = 0
   for i in range(numberOfStudent):
       sumInitialize += listOfStudent[i]

   return (sumInitialize / numberOfStudent)


# main program---->>

loop = True
listOfStudent = []
numberOfStudent = int(input("Enter No of Student: "))
count = 1

for i in range(numberOfStudent):
   marks = int(input(f"Enter marks for student {count}: "))
   listOfStudent.append(marks)
   count += 1

   print(
       "--------------------Select Your Choice From Following list-----------------\n1) Enter 1 for Average\n2) Enter 2 for Maximum\n3) Enter 3 for Minimum\n4)Enter 4 for Largest Marks Frequency\n5)Enter 5 for minimum Marks Frequency\n6)Enter 6 for Count of absent student\n7) Enter 7 to create new list of marks\n8) Enter 8 to exit")
