Write a program to check if the given number is Armstrong or not in python.

def is_armstrong(num):
# Calculate the number of digits in the number
num_digits = len(str(num))

# Initialize sum to store the result
sum = 0

# Temporary variable to store the original number
temp = num

# Calculate Armstrong sum
while temp > 0:
digit = temp % 10
sum += digit ** num_digits
temp //= 10

# Check if the number is Armstrong or not
if num == sum:
return True
else:
return False

# Input from the user
number = int(input(“Enter a number: “))

# Check if the number is Armstrong or not
if is_armstrong(number):
print(f”{number} is an Armstrong number.”)
else:
print(f”{number} is not an Armstrong number.”)

In this program the function is_armstrong() which takes a number as input and returns True if it’s an Armstrong number, otherwise False. It will prompt the user to enter a number and calls this function to determine if the entered number is an Armstrong number or not when executed.
