Practical No: -2
Experiment No. 2: Write a Python program to store marks scored in subject “Fundamentals of Data
Structure” by n students in the class. Write function 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
Code:
# Function for average score of the class
def average(listofmarks):
sum=0
count=0
for i in range(len(listofmarks)):
if listofmarks[i]!=-999:
sum+=listofmarks[i]
count+=1
avg=sum/count
print("Total Marks : ", sum)
print("Average Marks : {:.2f}".format(avg))
#<----------------------------------------------------------------------------------------------------->
# Function for Highest score in the test for the class

break
for i in range(1,len(listofmarks)):
if listofmarks[i]>Max:
Max=listofmarks[i]
return(Max)
#<------------------------------------------------------------------------------------------------------>
# Function for Lowest score in the test for the class
def Minimum(listofmarks):
for i in range(len(listofmarks)):
if listofmarks[i]!=-999:
Min=listofmarks[0]
break
for i in range(1,len(listofmarks)):
if listofmarks[i]<Min:
Min=listofmarks[i]
