Python program to calculate simple interests.

by

In this python basic program, we will calculate simple interests using the formula P+(P/r)*t.

Steps to solve the program
  1. Take the principal amount, rate of interest, and number of years as input.
  2. Calculate the simple interest using the formula P+(P/r)*t, where P is the principal amount, r is the rate of interest, t is the number of years.
  3. Print the output.
				
					p = 1000
r = 10
t = 2

amount = p+(p/r)*t

print("Amount payable: ",amount)

Output :

				
					Amount payable:  1200.0

print the current date in the given format

Check whether the given number is an Armstrong number.

by

In this python basic program, we will check whether the given number is an Armstrong number or not.

Steps to solve the program
  1. Take a number as input through the user.
  2. See the given example to understand what is an Armstrong number.
  3. Create a variable and assign its value equal to 0.
  4. While the number is greater than 0 divide the number by 10 using % and add the remainder raised to 3 to the variable that we have created.
  5. Now divide the number by 10 using //.
  6. If the value of the variable is equal to the input number then it is an Armstrong number.
  7. Print the output
				
					num = a = 153
rev = 0

while a>0:
    rem = a%10
    rev = rev +rem**3
    a= a//10
    
if rev == num:
    print("It is a armstrong number")
else:
    print("It is not a armstrong number")

Output :

				
					It is a palindrome number
