input: Write a function that takes two parameters, 'x' and 'y', and prints "x is greater than y" if x is greater than y, otherwise prints "y is greater than or equal to x".
  
  def print_comparison(x, y):
      if x > y:
          print(f'{x} is greater than {y}')
      else:
          print(f'{y} is greater than or equal to {x}')
  
  assert print_comparison(5, 3)=='5 is greater than 3'
  assert print_comparison(3, 5)=='5 is greater than or equal to 3'
  assert print_comparison(4, 4)=='4 is greater than or equal to 4'
output: def print_comparison(x, y):
      if x > y:
          print(f'{x} is greater than {y}')
      else:
          print(f'{y} is greater than or equal to {x}')
