Bug summary
By calling the built-in input() function after closing the plot within an animation object, I got a Tkinter exception.
Code for reproduction
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig, ax = plt.subplots()
graph, = ax.plot([], [])
def update_plt(t):
print(t)
graph.axes.plot([1,2], [4, t])
if t == 4:
plt.close()
return graph,
ani = animation.FuncAnimation(fig, update_plt, [r for r in range(10)],
blit=False, interval=500, repeat=False)
plt.show()
x = input() # <-- comment out, no exception.
print('Done.')Actual outcome
Exception in Tkinter callback
