添加图列，创建图列对象，然后用句柄函数handles添加即可。

 #设置图列plt.title("正余弦函数赛跑")from matplotlib.lines import Line2DsinLine=Line2D([0,1],[1,1],lw=3,ls=':',c='cornflowerblue',label=r'$y=\sin(x)$')#对象cosLine=Line2D([0,1],[1,1],lw=3,ls='-.',c='crimson',label=r'$y=\cos(x)$')  #对象#添加到图列plt.legend(handles=[sinLine,cosLine],ncol=2,loc='upper right')

保存动画用ani.save('001.gif'）如果想背景透明，把子图设置

plt.axis('off') #关闭坐标轴

ax.patch.set_facecolor('none') #子画布对象设置透明
