The animation example below (taken from
http://zulko.github.io/blog/2014/11/29/data-animations-with-python-and-moviepy/)
stops after producing and displaying the 41 frames. In stead, after producing
the 41 frames I want to make it loop continuously. I have googled and googled
and googled and still not found out how to do it. I guess that it is very
simple but how?
The program prints out some rather uninteresting information - how can I
suppress that?

import numpy as np
import mayavi.mlab as mlab
import moviepy.editor as mpy
duration= 2 # duration of the animation in seconds (it will loop)
# MAKE A FIGURE WITH MAYAVI
fig_myv = mlab.figure(size=(220,220), bgcolor=(1,1,1))
X, Y = np.linspace(-2,2,200), np.linspace(-2,2,200)
XX, YY = np.meshgrid(X,Y)
ZZ = lambda d: np.sinc(XX**2+YY**2)+np.sin(XX+d)
# ANIMATE THE FIGURE WITH MOVIEPY, WRITE AN ANIMATED GIF
def make_frame(t):
mlab.clf() # clear the figure (to reset the colors)
mlab.mesh(YY,XX,ZZ(2*np.pi*t/duration), figure=fig_myv)
return mlab.screenshot(antialiased=True)
animation = mpy.VideoClip(make_frame, duration=duration)
animation.write_gif("sinc.gif", fps=20)
