這篇文章主要講解了“如何使用Python實(shí)現(xiàn)windows倒計(jì)時(shí)鎖屏功能”,文中的講解內(nèi)容簡單清晰,易于學(xué)習(xí)與理解,下面請大家跟著小編的思路慢慢深入,一起來研究和學(xué)習(xí)“如何使用Python實(shí)現(xiàn)windows倒計(jì)時(shí)鎖屏功能”吧!
1)主要介紹了python實(shí)現(xiàn)windows倒計(jì)時(shí)鎖屏功能
python實(shí)現(xiàn)實(shí)windows倒計(jì)時(shí)鎖屏功能
# 倒計(jì)時(shí)鎖屏 import time from ctypes import * def closewindows(closetime): while closetime>0: print(closetime) time.sleep(1) closetime-=1 user32 = windll.LoadLibrary('user32.dll') user32.LockWorkStation() if __name__ == "__main__": closewindows(3)
2)知識點(diǎn)擴(kuò)展
Python在windows鎖屏的代碼
