我如何使这个程序停止运行?

Question

这是代码，如果您正在使用spyder，则必须在控制台中键入%matplotlib才能使其工作。动画停止运行，但仍有大量数字出现在控制台中。我该如何结束代码?

import matplotlib.pyplot as plt 
import matplotlib.animation as animation 
import numpy as np 
plt.style.use('dark_background')
fig = plt.figure() 
ax = plt.axes(xlim=(-50, 50), ylim=(-50, 50)) 
line, = ax.plot([], [], lw=2) 
# initialization function 
def init(): 
# creating an empty plot/frame 
line.set_data([], []) 
return line, 
xdata, ydata = [], [] 
x = 0
y = 0
# animation function 
def animate(i):
print(i)
t = i*0.1
y = 0
x = t
if x > 10 and y == 0:
i = 0
x = 10
y = t - 10
if y >10 and x == 10:
x = 10 - (t-20) 
y = 10
if (y < 10 or y == 10) and x <= 0 and y!=0:
y = 10 - (t-30)
x = 0
if y<0:
plt.stop()
exit()
print(y)
xdata.append(x)
ydata.append(y)
line.set_data(xdata, ydata)
return line,


# setting a title for the plot 
plt.title('Creating a moving point') 
# hiding the axis details 
plt.axis('off') 
# call the animator  
anim = animation.FuncAnimation(fig, animate, init_func=init, 
frames=500, interval=20, blit=True, repeat=False)

如果你想停止动画，那么在函数集中，例如，它将在第15次迭代时停止:

def animate(i):
if i == 15:
anim.event_source.stop()
