input: Write a function to classify numbers from 1 to 10 as even or odd.
  assert classify_numbers() == ['1 is odd', '2 is even', '3 is odd', '4 is even', '5 is odd', '6 is even', '7 is odd', '8 is even', '9 is odd', '10 is even']
output: def classify_numbers():
      result = []
      for i in range(1, 11):
          if i % 2 == 0:
              result.append(f"{i} is even")
          else:
              result.append(f"{i} is odd")
      return result
