python利用winreg生成桌面路径及实现扫描二维码图片返回相关信息

import winreg
def desktop_path():
    key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, r'Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders')
    desktop = winreg.QueryValueEx(key, "Desktop")[0]
    # print(desktop)
    return desktop
desktop_path()

name = input("请输入你的文件名（带后缀）:")
wenjian = r"C:\Users\knighthood\OneDrive\桌面\{}".format(name)

name = input("请输入你的文件名（带后缀）:")
wenjian = "{}\{}".format(desktop_path(), name)

img = Image.open(image)

barcodes = pyzbar.decode(img)

    for barcode in barcodes:
        barcodeData = barcode.data.decode("utf-8")

# -*- coding: utf-8-*-
from PIL import Image
import pyzbar.pyzbar as pyzbar
 
def QRcode_message(image):
    img = Image.open(image)
    # 因为一张图片可能是一张二维码，也可能里面有许多二维码
    barcodes = pyzbar.decode(img)
    for barcode in barcodes:
        barcodeData = barcode.data.decode("utf-8")
        print(barcodeData)
 
if __name__ == '__main__':
    QRcode_message('test.jpg')
