[Qixi Festival Special] Use python to realize beating love + love electrocardiogram + roses +...

Preface

What? ? Tomorrow is Chinese Valentine's Day? After learning python for so long, you still can’t write a confession code to your partner or crush?

I have to prepare a few for you.
There are the beating hearts that were popular last year, and there are other ones too. Come take a look and choose. After receiving the code, don’t forget to send it to others.

emmm, let me show you the effect first.

To get the code, click on the business card at the end of the article~

There are some others that I won’t go into here, but you can get them directly from the business card at the end of the article.

• Change the perspective of drawing the image, that is, the position of the camera, azim rotates along the z-axis, and elev along the y-axis

The text content in the middle can be customized and modified

fig = plt.figure(figsize=(6, 8))
ax = fig.gca(projection='3d')
elev = 22
azim = 2.5
ax.view_init(elev, azim)  # 改变绘制图像的视角,即相机的位置,azim沿着z轴旋转，elev沿着y轴

• Divide the circle into 50 equal parts according to the angle

u2 = np.linspace(0, 2 * np.pi, 50)

• Divide height 1 equally into 20 parts, the height range of rose stems

h2 = np.linspace(0, 4, 20)  

• xy values ​​repeated 20 times

x2 = np.outer(0.05 * np.sin(u2), np.ones(len(h2)))  
y2 = np.outer(0.05 * np.cos(u2), np.ones(len(h2)))  

• height corresponding to x, y

z2 = np.outer(np.ones(len(u2)), h2)
