Why isn't FuncAnimation repeating when I'm put repeat = True as a parameter?

Question

import matplotlib.image as mpimg
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
from matplotlib.widgets import Button
from matplotlib.widgets import Slider
fig = plt.figure()
image_list =  ['downloads/20120831_194836_aia.lev1_euv_12s_4k.jpg', 'downloads/20120831_194936_aia.lev1_euv_12s_4k.jpg', 'downloads/20120831_195036_aia.lev1_euv_12s_4k.jpg']

list = []


for raw_image in image_list:
    image1 = mpimg.imread(raw_image)
    real_image1 = plt.imshow(image1)
    list.append([real_image1])


def update_plot(t):
    print(t)
    return list[t]


anim = animation.FuncAnimation(fig, update_plot, repeat = True, interval=1, blit=False,
                                repeat_delay=200)
plt.show()

I am trying to create a func animation with the 3 jpg images in the list. After the program runs the 3 images 1 time, it gives me an error. When I print 't', it never resets to 0.

Error:

Does anyone know what the issue is?

Answer 1

Solved it. I had to add frames = len(list) as a parameter of FuncAnimation
