python编程实现随机生成多个椭圆实例代码

import matplotlib.pyplot as pltimport numpy as npfrom matplotlib.patches import EllipseNUM = 250ells = [Ellipse(xy=np.random.rand(2) * 10,    width=np.random.rand(), height=np.random.rand(),    angle=np.random.rand() * 360)  for i in range(NUM)]fig, ax = plt.subplots(subplot_kw={'aspect': 'equal'})for e in ells: ax.add_artist(e) e.set_clip_box(ax.bbox) e.set_alpha(np.random.rand()) e.set_facecolor(np.random.rand(3))ax.set_xlim(0, 10)ax.set_ylim(0, 10)plt.show()
