这个是我从别人那边download下来的。生成的是这样的

这个会比较复杂并且是静态的.

下面这个会比较简单，并且可以做成动态GIF格式的
from MyQR import myqr
import os
words=“https://blog.csdn.net/Bdingse/article/details/89219172” # 给一个你要的地址
version, level, qr_name = myqr.run(
words,
version=1,
level=“H”,
picture=“dg4.jpg”, # 你提供的图片，要确保图片和代码在统一路径下
colorized=True, # true则是彩色的，false的话就是黑白
contrast=1.2, #对比度
brightness=1.2, #亮度
save_name=“p4.gif”, # 生成的二维码，
save_dir=os.getcwd() # 保存
)
结果:
