Matplotlib animation either freezes after a few frames or just doesn't work

Question

I\'ve been trying for hours to get this simple script working, but nothing I do seems to help. It\'s a slight modification of the most basic animated plot sample code from t

greetings from the future.

Here's how you'd do it in python 3:

import matplotlib
matplotlib.use('TkAgg') # Qt4Agg gives an empty, black window
import matplotlib.pylab as plt
import time

# create initial plot
z = zeros(10)
line, = plot(z)
ylim(-3, 3)

for i in range(60):
    print('frame:', i)

    d = randn(10)
    line.set_ydata(d)
    draw()
    #replace time.sleep() with plt.pause()
    plt.pause(0.5)

I got rid of the call to ion() and hold(False). I also replaced time.sleep with plt.pause
