Write a program to print all Armstrong numbers in a given range. Note: An Armstrong number is a number whose sum of cubes of digits is equal to the number itself. E.g. 370=33+73+03

                    
  # Program to print Armstrong numbers in a given range
  start = int(input("Enter starting number: "))
  end = int(input("Enter ending number: "))
  
  for n in range(start, end + 1):
      temp = n
      sum = 0
      digits = len(str(n))
  
      while temp != 0:
          rem = temp % 10
          sum += rem ** digits
          temp = temp // 10
  
      if n == sum:
          print(n, end=' ')
                    
                    

Python Program to print Hello World!

                    
  print("Hello World!")

  print('''Hello World!''')
                    
                    

Python Program to Add Two Numbers

  
  # This Python  program adds two numbers
  
  num1 = 14
  num2 = 25
  
  sum = num1 + num2
  
  print('The sum of ', num1, ' and ', num2, ' is ', sum)

  

Python Program to Add Two Numbers From the User

    
  num1 = input('Enter first number: ')
  num2 = input('Enter second number: ')
  
  # Add two numbers
  sum = float(num1) + float(num2)
  
  # Display the sum
  print('The sum of ', num1, ' and ', num2, ' is ', sum)
