最近寢室網不太好，經常莫名其妙的連不上網。害的我上次一個上午沒有收集到數據。其實也簡單，每次手動在自己寢室和隔壁寢室之間切換就可以了。。。那我不在電腦旁邊的時候誰來切？還是編個自動切換wifi的程序吧:-) 以后迅雷下載的時候也有用呢:-)
為了便于在其他程序中調用，這個程序被做成了模塊的形式。
# 再一次感到了Python用來做開發時的便利性，可以快速把想法付諸實施。這次這個程序用了一個多小時就完成了~
# 借此機會練習了一下正則表達式，真是神器~ Python可以和CMD做聯合編程，就是說以前學的CMD的技術也可以用上了，好爽~
調用方式：（放在同一個文件夾下）
importkol
kol.func()
為了隱私，wifi的SSID已經隱去，請按需要修改。
