Draw Bing DwenDwen and Shuey RhonRhon with Python

With the convening of the 2022 Beijing Winter Olympics, Bing DwenDwen and Shuey RhonRhon instantly jumped to “top traffic”. What if we can’t get it? Let’s write the code to create them! 

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
from matplotlib.patches import Rectangle

plt.rcParams['font.sans-serif']=['Comic Sans MS']

The basic idea of ​​the code is actually very simple, that is to keep drawing ellipses. In order to simplify the code, we write a function to draw ellipses.

def ellipse(el, edgecolor='black', facecolor='w', n=0, alpha=1):

    axs[n].add_patch(el)
    el.set_facecolor(facecolor)
    el.set_alpha(alpha)
    el.set_edgecolor(edgecolor)
