Write a function that takes in a number. Print a pyramid that is that many "rows" tall. Kind of like this...

def aliensMadeThePyramids(num):

  # Assuming that each row will be two rows longer than the previous, then
  # that means the bottom row will have 2*n + 1 "bricks" in it and zero 
  # spaces in front of it

  # ...and the one before that will have 1 space in front of it...

  # ...and the one before that will have 2 spaces in front of it...

  # ...and the top row will have num spaces in front of it...

  # so lets start out our number of spaces at num and our number of
  # bricks with 1
  spaces = num
  bricks = 1

  # Now we'll make a for loop that'll go from the top to the bottom.
  # Note: This is not a good way to construct a pyramid in real life.

  for layer in range(num):

    print spaces * " " + bricks * "t"

    # now we ensure that the next row will have two REMOVED bricks in it...
    bricks = bricks + 2

    # and that the next row will have one less space in it...
    spaces = spaces - 1
