Python3如何实现Win10桌面自动切换_Python

得空写了个自动切换桌面背景图片的小程序。再不写python就要扔键盘了，对vue还有那么一点好感，天天php真是有够烦。

准备工作

准备个文件夹放在桌面上，平时看到什么高清好图就拽进去。

Python3如何实现Win10桌面自动切换

运行脚本

脚本如下：

									#!/usr/bin/python

									import ctypes

									import osimport random

									import functools

									import schedule

									index = 0

									def change_background(picture_path: str) -> None:

									  ctypes.windll.user32.SystemParametersInfoW(20, 0, picture_path, 3)

									def get_pictures(dir_path: str) -> list:

									  return [os.path.join(root, name)

									      for root, dirs, files in os.walk(dir_path, topdown=False)

									      for name in files

									      if name.endswith('jpg') or name.endswith('png')]

									def log(text):

									  def decorator(f):

									    @functools.wraps(f)

									    def wrap(*args, **kwargs):

									      p = f(*args, **kwargs)

									      print(f'{text}: {p}')

									      return p

									    return wrap

									  return decorator

									@log(f'DESKTOP_BG_IMG switch to')

									def change_background_job(dir_path) -> None:

									  if dir_path.__class__.__name__ == 'list':

									    dir_path = dir_path[0]

									  pictures = get_pictures(dir_path)

									  index = random.randint(0, len(pictures) - 1)

									  change_background(pictures[index])

									  return pictures[index]

									def scheduler(job: staticmethod, interval, arg_num, *args) -> None:

									  if arg_num <= 0:

									    schedule.every(interval).seconds.do(job)

									  else:

									    schedule.every(interval).seconds.do(job, [args[i] for i in range(arg_num)])

									  while True:

									    schedule.run_pending()

									if __name__ == '__main__':

									  scheduler(change_background_job, 10, 1, r'C:\Users\zenkilan\Desktop\test_pictures', 'hello', 'world')
