input: Write a function to compare two numbers 'x' and 'y' and print "x is greater than y" if x is greater than y, otherwise print "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}')

output: def print_comparison(x, y):
