fig, ax = plt.subplots()

x = np.arange( 0, 2 * np.pi, 0.01)
line, = ax.plot(x, np.sin(x))


def animate(i):
line.set_ydata(np.sin(x + i / 100))
return line,


def init():
line.set_ydata(np.sin(x))
return line,


ani = animation.FuncAnimation(fig=fig, func=animate, frames= 100,
init_func=init, interval= 20, blit=False)
