Python generates QR code for picture

Imge.show () may not work under Liunx.

PS: The standard version of the show () method is not very efficient because it first saves the image as a temporary file and then displays it using XV. If XV is not installed, the function does not even work. However, this method is very convenient for debug and test. (The default picture viewer should be called in Windows to open)

The code is as follows:

#-*-coding:utf-8-*-

#这是一个二维码的生成代码

Import QRCode

Import OS

From PIL import Image

Import Pillow

Print ()

Class QRCode ():

def __init__ (self, version=8,
