How to draw lines and rectangles

def addVerticalLine(picture, atX, color):
  for y in range(1, getHeight(picture)+1):
    pixel = getPixel(picture, atX, y)
    setColor(pixel, color)

def drops(): # Takes ages
  pic = makeEmptyPicture(300, 300)
  show(pic)
  for x in range(100, 200):
    addVerticalLine(pic, x, blue)
  repaint(pic)

def line(): # Very fast
  pic = makeEmptyPicture(300, 300)
  show(pic)
  for x in range(100, 200):
    addLine(pic, x, 1, x, getHeight(pic), blue)
  repaint(pic)

def rect(): # Very, very fast
  pic = makeEmptyPicture(300, 300)
  show(pic)
  addRectFilled(pic, 100, 1, 100, getHeight(pic), blue)
  repaint(pic)
