Python matplotlib display

Say I have a function plot(I) to plot an image like

def plot(I):
    plt.imshow(I)
    time.sleep(0.5)
    plt.show(block=False)

And in my main program, I have a loop to update I like

if __name__ == "__main__":
    I=some_input
    for i in range(300):
        I=update(I)
        plot(I)

I want to display the updated images like a gif file but the code above failed like the plot does not update and I have to close the window so that it can be updated. Is there any way to achieve what I want like display images consecutively with matplotlib.

I got it now. This should do the trick.

def plot(I):
    plt.imshow(I,'gray')
    plt.show(block=False)
    plt.pause(0.5) 
    plt.clf()

This will plot I every 0.5 second.
