Assignment No:05

Problem Statement: Develop a program to read the student details like name, USN and marks in 3 subjects. Display the student details, total marks and percentage with suitable messages

Aim: To implement class by using student entity.

Theory:

Algorithm:

a) Algorithm for display the student details, total marks and percentage with suitable messages

Step 1: Start

Step 2: Accept student name, USN and marks of three subjects (FPP, AC, SPM)

Step 3: using function find out the total of three subjects.

Step 4: Using function find out the percentage of students.

Step 5: Display all the details of student.

Step 6: Stop

Flowchart:

Conclusion: Hence, we learn how to implement the class in python along with its object creation and calling of functions as per the priority user requirement. 

Develop a python program using class concept to display student details.

First of all we have to write an algorithm for the same:

Step1: Start

Step2: Accept student details from the user.

Step3: Find out the total of all three subjects.

Step4: Find out the percentage of marks.

Step5: Show the student information.

Step6: Stop

As we know we are implementing this assignment by using the concept of class are as follows:

Created class student with parameterized constructor.

Five data members with public access specifier. One show_student( ) method to display student information, accept_info( ) method to accept all details of students from the user at runtime, find_total() method to find total of three subjects, find_percentage() method to compute percentage of marks.

Line no 43 we have created one object s1 of student with details. so when object is going to be created the memory is going to be allocated for particular object and then corresponding methods are going to be called for that object.

After Executing this code you will see the output like this:

Python program to check whether number is palindrome or not also count number of occurrences of each digit.

First of all, we have to write an algorithm for the same so that we come to know how to solve this problem statement step by step.

Algorithm:

1. Start

2. Accept any number n from the user.

3. Using function reverse the accepted number n.

4. Check whether the original and reverse number are same if yes then given number is palindrome.

5. If original and reverse number both are not same, then number is not palindrome.

6. Using function compute each digit occurrence inside the accepted number n.

7. Stop

Now, start the implementation of above algorithm step by step using python.

n = int (input ("Enter the Number n: "))

rev = reverse_num(n) # Function calling to reverse the given number.

if (rev = = n):

    print ("The number is palindrome")

else:

    print ("The number is not palindrome")

ocuurance_of_each_digit(n): # Function calling to find occurrence of each digit.

----------------------------------------------------------------------------------------------------------------------

# Function definition: To reverse the number.

def reverse_num(num):

    reverse = []

    while num >= 1:

        rem = int (num % 10)

        reverse.append(rem)

        num = num / 10

    print(reverse) # get number in reverse order but in list, so we want convert list to str

    temp=""

    for no in reverse:

            temp = temp + str(no)

    rev1 = int (temp) # now converting string to integer

    return rev1

-----------------------------------------------------------------------------------------------------------------------

 

----------------------------------------------------------------------------------------------------------------------

# Function definition: To find the occurrence of each digit in given number.

def ocuurance_of_each_digit(num):

    count = [0,0,0,0,0,0,0,0,0,0]

    while n >= 1:

        digit = int (n % 10)

        count[digit] = count[digit] + 1

        n = n / 10

length = len(count)

i = 0

while i < length:

    if count[i]! = 0:

        print(f"{i} occurance is:", count[i])

    i = i+1

-----------------------------------------------------------------------------------------------------------------------
