				?

									import qrcode

									qr = qrcode.QRCode(

									    version=5,

									    error_correction=qrcode.constants.ERROR_CORRECT_L,

									    box_size=10,

									    border=4,

									)

									qr.add_data('https://blog.csdn.net/boysoft2002/article/details/120213715')

									qr.make(fit=True)

									img = qr.make_image(fill_color="black", back_color="white")

MyQR

下载地址：

MyQR · PyPI

https://pypi.org/project/MyQR/

使用简介：

				?

									from MyQR import myqr

									myqr.run(words = 'https://blog.csdn.net/boysoft2002/article/details/120257133',

									         save_name = 'qrcode.jpg'

									         ) 

									#生成带背景图片的二维码

									myqr.run(words = 'https://blog.csdn.net/boysoft2002/article/details/120242318',

									         picture = r'background.jpg',  #支持动态gif作背景

									         colorized = True,　# True：彩色，False：黑白

									         save_name = 'qrcode.png'

									         )

安装第三方库

如下二选一安装都可以，若存在其它依赖库请一并安装：
