用python 寫了一個爬取ip位址的爬蟲，由於網站是反爬蟲的，所以寫了代理
使用線程池開啟10個線程來爬取ip位址
然而直接報錯'list ' object has no attribute 'get'
不知道如何解決，貼上本人程式碼。

makeRequests是做什麼的？你是不是把requests賦值成了list類型，下面再requests.get(*)自然就出錯了吧。
makerequests類似python的map函數，裡面有兩個參數（function，list（）），以list裡面的參賽供給給前面的函數進行運作……
裡面的requests是requests模組的方法，可能重名了吧，又或者url[0]這個寫法是錯的，等下回去調試一下…
重名了，建議這一行
先改成
再試試
