因为觉得win10锁屏页面比较好看，有时候能够根据日期变换，因此写个脚本获取锁屏页面

win10原生锁屏

根据查阅资料，win10的锁屏图片保存在C:\Users\你的用户名\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets，根据win10社区所说cw5n1h2txyewy是随机生成的，不过我发现的都是这个，也许其他版本的win10不太一样吧。这里面的文件需要添加.jpg后缀才是我们需要的图片。

代码

import os
import shutil
import argparse

# win10 screen lock version

src = os.path.expanduser(
    "~\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager_cw5n1h2txyewy\LocalState\Assets")

dst = os.path.expanduser("~\Pictures\Saved Pictures\lock")

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('-d', '--dst', help='dst path', type=str, default=dst)
    args = parser.parse_args()

    dst = args.dst

    if not os.path.exists(dst):
        os.mkdir(dst)

    # remove duplicate filename
    srcFilenames = set(os.listdir(src))
    dstFilenames = os.listdir(dst)
    dstFilenames = [filename.replace('.jpg', '') for filename in dstFilenames]
    dstFilenames = set(dstFilenames)
    lackFilenames = srcFilenames - dstFilenames

    # copy file
    for filename in lackFilenames:
        srcFile = os.path.join(src, filename)
        dstFile = os.path.join(dst, filename)+'.jpg'
        shutil.copyfile(srcFile, dstFile)

Lenovo锁屏

联想电脑助手会接管win10的原生锁屏，通过everything观察文件变化可以查到联想锁屏的位置在C:\ProgramData\Lenovo\devicecenter\LockScreen\cache，且以jpg格式存好了，可惜的是大部分图片原本就有联想的二维码或者水印。

代码

import os
import shutil
import argparse

# lenovo screen lock version

src = "C:\ProgramData\Lenovo\devicecenter\LockScreen\cache"

dst = os.path.expanduser("~\Pictures\Saved Pictures\lock")


def get_filelist(dir, extract):
    filelist = []
    filenames = os.listdir(dir)
    for filename in filenames:
        ext = os.path.splitext(filename)[-1]
        if ext == extract:
            filelist.append(filename)
    return filelist


if __name__ == '__main__':

    parser = argparse.ArgumentParser()
    parser.add_argument('-d', '--dst', help='dst path', type=str, default=dst)
    parser.add_argument('-s', '--src', help='src path', type=str, default=src)
    args = parser.parse_args()

    dst = args.dst
    src = args.src

    if not os.path.exists(src):
        exit("src path not found")

    if not os.path.exists(dst):
        os.mkdir(dst)

    # ignore zip
    srcFilenames = set(get_filelist(src, '.jpg'))
    dstFilenames = set(os.listdir(dst))
    # remove duplicate filename
    lackFilenames = srcFilenames - dstFilenames

    # copy file
    for filename in lackFilenames:
        srcFile = os.path.join(src, filename)
        dstFile = os.path.join(dst, filename)
        shutil.copyfile(srcFile, dstFile)
