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，

1. #import numpy as np  # 这行删除吧，没有用上。
   
2. import matplotlib.pyplot as plt
   
3. import matplotlib.patches as pat
   
4. 
   
5. fig, axs = plt.subplots(1, 2, sharex=False, sharey=False)
   
6. cic = pat.Circle((0, 0), 5, fill=False, color='b')  # 圆心坐标0,0，半径5
   
7. axs[0].add_patch(cic)
   
8. axs[0].set_xlim(-5.5, 5.5)
   
9. axs[0].set_ylim(-5.5, 5.5)
   
10. 
    
11. xy = [[0, 5], [5, - pow(75, 0.5)], [-5, - pow(75, 0.5)]]  # 三角形的三个顶点的坐标
    
12. tra = pat.Polygon(xy, True, fill=False, color='g')
    
13. axs[1].add_patch(tra)
    
14. axs[1].set_xlim(-5.5, 5.5)
    
15. axs[1].set_ylim(-10, 5.5)
    
16. 
    
17. 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
