input: Write a function to print "x is greater than y" when x is greater than y, otherwise print "y is greater than or equal to x". The function should take two parameters: 'x' and 'y'.
  
  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) # Expected output: "5 is greater than 3"
  assert print_comparison(2, 7) # Expected output: "7 is greater than or equal to 2"
  assert print_comparison(4, 4) # Expected output: "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}')
