input: Write a function named printMax that takes two parameters, parameter_1 and parameter_2, and prints out the larger of the two parameters. If both parameters are equal, it should print either of them.
  assert printMax(7, 9)==None
  assert printMax(10, 5)==None
  assert printMax(8, 8)==None
output: def printMax(parameter_1, parameter_2):
      if parameter_1 >= parameter_2:
          print(parameter_1)
      else:
          print(parameter_2)
