Question

如何在自动执行后关闭python动画，以便可以执行其余的程序？例如，我有以下代码显示第一个动画，但我必须在代码进入第二个动画之前手动关闭它。

更新

import matplotlib.pyplot as plt
import numpy as np
from PIL import Image
from matplotlib.animation import FuncAnimation

plt.style.use('classic')


def update(step,arr,axis,max_step):

    print(step,max_step)

    for i in range(5):
        for j in range(5):
            axis[i, j].xaxis.set_major_locator(plt.NullLocator())
            axis[i, j].yaxis.set_major_locator(plt.NullLocator())
            if arr[step][i, j] == 10:
                axis[i, j].imshow(Image.open('A.jpg'), cmap="bone")
            else:
                axis[i, j].imshow(Image.open('B.jpg'), cmap="bone")

    if step>=max_step:
        plt.close()
    return axis

if __name__ == '__main__':

    a = []
    for i in xrange(5):
        temp = np.zeros((5, 5))
        temp[i, i] = 10
        a.append(temp)

    fig, ax = plt.subplots(5, 5, figsize=(5, 5))
    fig.subplots_adjust(hspace=0, wspace=0)

    # FuncAnimation will call the 'update' function for each frame; here
    # animating over 10 frames, with an interval of 200ms between frames.
    anim = FuncAnimation(fig, update, frames=5, fargs=(a, ax,4), interval=200, repeat=False)

    plt.show()

    # repeat the above procedure
    a = []
    for i in xrange(5):
        temp = np.zeros((5, 5))
        temp[i, i] = 10
        a.append(temp)

    fig, ax = plt.subplots(5, 5, figsize=(5, 5))
    fig.subplots_adjust(hspace=0, wspace=0)

    # FuncAnimation will call the 'update' function for each frame; here
    # animating over 10 frames, with an interval of 200ms between frames.
    anim = FuncAnimation(fig, update, frames=5, fargs=(a, ax,4), interval=200, repeat=False)

    plt.show()

使用评论中的建议，上面的代码实际上有效，但我也收到了这个错误：

是否有解决此错误的想法？
