用pyhton化x**2+y**2

要使用Python绘制函数 f(x, y) = x^2 y^2 的图像，您可以使用matplotlib库来完成。下面是一种可能的方法：

from matplotlib import pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np

fig = plt.figure()
ax = Axes3D(fig)

x = np.arange(-5, 5, 0.1)
y = np.arange(-5, 5, 0.1)
x, y = np.meshgrid(x, y)

def fun(x, y):
    f = x**2 * y**2
    return f

f = fun(x, y)

ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('f')

ax.text2D(0.3, 0.95, "函数f(x, y) = x^2  y^2的函数曲线", transform=ax.transAxes)

ax.plot_surface(x, y, f)

plt.show()

这段代码使用numpy库生成了x和y的坐标网格，并定义了函数fun计算对应的f值。然后使用matplotlib的Axes3D模块来创建一个三维坐标系，并绘制了函数的曲面图像。最后使用plt.show()显示图像。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
