最近寢室網(wǎng)不太好，經(jīng)常莫名其妙的連不上網(wǎng)。害的我上次一個(gè)上午沒(méi)有收集到數(shù)據(jù)歧杏。其實(shí)也簡(jiǎn)單镰惦，每次手動(dòng)在自己寢室和隔壁寢室之間切換就可以了。犬绒。旺入。那我不在電腦旁邊的時(shí)候誰(shuí)來(lái)切？還是編個(gè)自動(dòng)切換wifi的程序吧:-) 以后迅雷下載的時(shí)候也有用呢:-)
為了便于在其他程序中調(diào)用凯力，這個(gè)程序被做成了模塊的形式眨业。
# 再一次感到了Python用來(lái)做開(kāi)發(fā)時(shí)的便利性，可以快速把想法付諸實(shí)施沮协。這次這個(gè)程序用了一個(gè)多小時(shí)就完成了~
# 借此機(jī)會(huì)練習(xí)了一下正則表達(dá)式龄捡，真是神器~ Python可以和CMD做聯(lián)合編程，就是說(shuō)以前學(xué)的CMD的技術(shù)也可以用上了慷暂，好爽~
調(diào)用方式：（放在同一個(gè)文件夾下）

為了隱私聘殖，wifi的SSID已經(jīng)隱去，請(qǐng)按需要修改行瑞。
