In this simple python program, we need to check for an Armstrong number. It's a beginner-level python program.
To understand this example, you should have knowledge of the following Python programming topics:
In this basic python program, we need to know what is mean by an Armstrong number. Armstrong number is a number in which the sum of the cube if total digits in the number will be equal to the number itself.
For example, let us take the example of a number 153 and so to check that number is Armstrong number or not, we need to take the cube of 1 and 5 and 3 and add that cubes together and check the result is equal to 153 or not using an if condition in python. If it's 153, it's Armstrong's number. Else not. Here 1+125+27 =153, so it is an Armstrong number.
In this simple python program, We have to accept the user's number and initialize the sum and temp variables. Use a
while loop in python until the number is greater than zero. Split the number into digits using mod operator by 10 and calculate the sum of every digit's cube in a number. Finally, divide the number by 10 removing one digit from the number. Then take the cube of that digit and sum the digit cube with others.
STEP 1: Accept the number from the user to check for Armstrong using the input function in the python programming language and convert that string to an integer using int().
STEP 2: Initialize the sum as zero and use a temp variable to save the number from the user.
STEP 3: Add a
while loop for splitting the number from the user and calculating the sum of the cube of each digit.
STEP 4: Take one digit from the number using the mod operator.
STEP 5: Calculate the sum as sum + cube of that digit.
STEP 6: Divide the number with 10 to remove that digit and continue the loop.
STEP 7: Use an if condition to check the num = sum, and if it is correct, print the number is Armstrong else, not Armstrong using the print statement in python language.
number = int(input("Enter a number: ")) sum = 0 temp = number while temp > 0: integer = temp % 10 sum += integer ** 3 temp //= 10 if number == sum: print(number,"is an Armstrong number") else: print(number,"is not an Armstrong number")
Enter a number: 153 153 is an Armstrong number
