  def f(n):
      for i in range(1, 11):
          print("{} * {} = {}".format(n, i, n*i))
  assert f(5) is None  # This will print the multiplication table for 5
  assert f(7) is None  # This will print the multiplication table for 7
output: def f(n):
      for i in range(1, 11):
          print("{} * {} = {}".format(n, i, n*i))
