Python網(wǎng)絡數(shù)據(jù)采集-第2版-(影印版) 內(nèi)容簡介
如果編程是魔法，那么網(wǎng)絡數(shù)據(jù)采集肯定就是某種巫術。編寫一個簡單的自動化程序，你就可以查詢Web服務器，請求數(shù)據(jù)，解析數(shù)據(jù)以提取所需的信息。這本實用書籍的擴充版不但介紹了網(wǎng)絡數(shù)據(jù)采集，更是從現(xiàn)代網(wǎng)絡中抓取幾乎各類數(shù)據(jù)的綜合指南。 瑞安·米切爾著的《Python網(wǎng)絡數(shù)據(jù)采集(第2版影印版)(英文版)》**部分側重于網(wǎng)絡數(shù)據(jù)采集機制：使用Python向Web服務器請求信息，對服務器響應信息做基本的處理，自動與站點展開交互。第二部分探討了各種更具體的工具和應用程序，以應對你可能遇到的任何網(wǎng)絡數(shù)據(jù)采集場景。
