input: Write a function that takes two parameters and prints out the larger of them. The function should be named `printMax` and should handle any number inputs. 
  assert printMax(7, 9)==9
  assert printMax(5, 3)==5
  assert printMax(0, 0)==0
  assert printMax(-1, -5)==-1
  assert printMax(10, -10)==10
output: def printMax(a, b):
      if a > b:
          return a
      else:
          return b
