在Python中,我们可以使用qrcode库来生成二维码。而qrcode库中的decode函数则可以用来解码已有的二维码图片。decode函数的语法如下: importqrcodefromPILimportImagefrompyzbar.pyzbarimportdecodedefdecode_qrcode(image_path):image=Image.open(image_path)result=decode(image)iflen(result)>0:data=result[0].data.decod...
此处并没有使用add_data()添加数据,make_image()生成二维码,而是使用qrcode.make(data)的方式获取im对象。qrcode.make()是qrcode提供简单调用接口。 - 2. 正常生成二维码的步骤: 创建QRCode对象 add_data()添加数据 make_image()创建二维码(返回im类型的图片对象) 自动打开图片,im.show() - 3. QRCode参数详...

no, decoding and decrypting are not the same. decoding is generally a reversible, algorithmic process where you transform data back to its original form. on the other hand, decryption is a security measure to restore encrypted data using a specific key. while you decode something that has been...
