Open python file, write code to plot a circle step by step The equation for a circle isx^2 + y^2 = 1, therefore,y = +sqrt(1-x^2)andy = -sqrt(1-x^2). SelectSoltuion Explorer, double click on the python file to open it, in my side, the file name isPythonApplication1.py....
1. 调用包函数绘制圆形Circle和椭圆Ellipse frommatplotlib.patchesimportEllipse,Circle importmatplotlib.pyplotasplt fig=plt.figure() ax=fig.add_subplot(111) ell1=Ellipse(xy=(0.0,0.0),width=4,height=8,angle=30.0,facecolor='yellow',alpha=0.3) cir1=Circle(xy=(0.0,0.0),radius=2,alpha=0.5) ax.a...
axes.plot(x,-y)# 下半部 plt.axis('equal')plt.title('圆形绘制2')#===plt.show() 其实最简单的圆还得看下面这个:这里我们使用的是turtle,直接利用自身所带的函数color设置颜色,circle就是设置圆的半径,最后显示就行。很痛快的。 代码语言:javascript 复制 importturtle turtle.color('red')turtle.circle...
