is it possible to animate molecule rotation using for loop in pymol?

Question

Is it possible to animate a molecule in pymol with several rotate commands using a for loop? or do i have to use moviemaking to do this?

I tried this to animate the molecule

for angle in range(0,360,20):
  cmd.rotate('x', angle)
  time.sleep(5)

but the script took unusually long to load and I think I only saw the end result (=molecule rotated in 360 degrees) as opposed to each step. How can I display the result of each rotate command?
