需要注意的：文章來源地址http://www.zghlxwxcb.cn/news/detail-509257.html

1. 我用了with語句保證瀏覽器實(shí)例在函數(shù)結(jié)束后正確關(guān)閉。
2. 我用了幾個(gè)try-except塊處理在各個(gè)步驟可能出現(xiàn)的異常，它可以在異常的時(shí)候打印出錯(cuò)誤的信息。
3. 我把大部分代碼封裝在一個(gè)函數(shù)中，你如果需要，就可以輕輕松松再次調(diào)用該函數(shù)或者用作其他腳本的部分。

到了這里，關(guān)于基于Python和Selenium的大麥網(wǎng)自動(dòng)搶票腳本的文章就介紹完了。如果您還想了解更多內(nèi)容，請(qǐng)?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
