看报错解决问题，希望得到帮助

我在Python写玫瑰花时遇到的问题，自己一个人没有头绪，搞了很久，哦所以求助于这么一个平台我希望获得帮助

importnumpyas n
import matplot1ib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
fig plt.figure(figsize=(6,6))
ax =fig.gca(projection='3d')
[x,t]=
n.meshgrid(n.array(range(25))/24.0,n.arange(0,575.5,0.5)/57520n.pi+4n.pi)
P= (n.pi/2)n.exp(-t/(8n.pi))
change = n.sin(15t)/150
u=1-(1-n.mod(3.3t,2n.pi)/n.pi)*4/2+change
y =2(×☆☆2-x)☆2n.sin(p)
= u(xn.sin(p)+yn.cos(p))
h=u*(xn.cos(p)-yn.sin(p))
C=plt.get_cmap('Blues')
surf = ax.plot_surface(rn.cos(t),rn.sin(t),h,rstride=
1,cstride=1,cmap=c,linewidth=0,antialiased=True)
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])
plt.slow([])
