python

利用matplotlib绘制一幅具有两个子图的图片# 第一个子图为半径为5的圆形，第2个子图为一个边长为10的等边3角形


怎么用matplotlib绘制图形啊刚学老师让我们自己研究怎么做都做不出来，呜呜，

#import numpy as np# 这行删除吧，没有用上。
import matplotlib.pyplot as plt
import matplotlib.patches as pat

fig, axs = plt.subplots(1, 2, sharex=False, sharey=False)
cic = pat.Circle((0, 0), 5, fill=False, color='b')# 圆心坐标0,0，半径5
axs.add_patch(cic)
axs.set_xlim(-5.5, 5.5)
axs.set_ylim(-5.5, 5.5)

xy = [, , [-5, - pow(75, 0.5)]]# 三角形的三个顶点的坐标
tra = pat.Polygon(xy, True, fill=False, color='g')
axs.add_patch(tra)
axs.set_xlim(-5.5, 5.5)
axs.set_ylim(-10, 5.5)

plt.show()

你库装好了吗，如果import部分报错就是没装库，还有楼上的答主第一行代码可以删了，没用
