2.   Write a program to store two integer values in two variables and using them calculate addition, subtraction, multiplication division.
3.   Write a program to print pay-slip using the following data.
Employee number is 100
Basic salary is 5000
DA must be calculated as 10% of basic
HRA must be calculated as 20% of basic
Total salary must be calculated as Basic+DA+HRA
 
4.   Write a program to calculate total marks and percentage of a student of 5 subjects and based on the percentage display the grade according to the following criteria.

 

Below 30%          D
30-45                   C
45-55                   B

Less than 5 years                 5%

 

6.   Write a program to find the Factorial of a number

num = int(input(“Enter a number: “))

fact= 1

# check if the number is negative, positive or zero

if num < 0:






   print("Sorry, factorial does not exist for negative numbers")





elif num == 0:





   print("The factorial of 0 is 1")





else:





   for i in range(1,num + 1,1):





       fact= fact*i





   print("Factorial: ",fact)





Output:





Enter a number: 5





Factorial: 120





 





7.   Write a program to find maximum of two numbers using function.





 





 





def maximum(a, b):





           





           if a >= b:





                        return a





           else:





                        return b





           





print(maximum(2, 7))





 





 





Output:





 





7





Method 2: Using inbuilt max() Function





 





a=int(input("Enter 1st number: "))

b=int(input("Enter 2nd number: "))

print("Larger number is", max(a,b))





 





Output:





 





Enter 1st number: 4





Enter 2nd number: 3





Larger number is:  7





 





 





8.   Python Program to Find Area of a Circle using function.





def findArea(r):





    PI = 3.142





    return PI * (r*r);





print(“Area is %.2f” % findArea(5));





 





 





9.   Find the Factorial of a Number Using Function





def factorial(n):





    if n < 0:





        return 0





    elif n == 0 or n == 1:





        return 1





    else:





        fact = 1





        while(n > 1):





            fact *= n





            n -= 1





        return fact





num = 5





print(“Factorial of”,num,”is”,





factorial(num))





Output:





Factorial of 5 is 120





10.           Find the Factorial of a Number Using Recursive approach





def factorial(n):





    if (n==1 or n==0)





          return 1





    else n * factorial(n – 1)





print(“Factorial of”,num,”is”,factorial(5))





Output:





Factorial of 5 is 120
