上次是wxWidget,這次又發現一個cURL。python版本分別叫做wxPython和pycurl。
wxWidget並不能算是一個特別牛的庫,至少介面設計上還是MFC層級的,對xml也沒有能用的支援,拼個介面很累。但是你猜不到的是,就這麼爛的介面,用Python寫出來的程式依然不長。
還有人用Python寫Win32的視窗程序,也不長。
今天用到個libcurl,把C++版的測試代碼和Python版本貼出來對比一下。
import pycurlimport StringIO url = "http://www.google.com/"crl = pycurl.Curl()crl.setopt(pycurl.VERBOSE,1)crl.setopt(pycurl.FOLLOWLOCATION, 1)crl.setopt(pycurl.MAXREDIRS, 5)crl.fp = StringIO.StringIO()crl.setopt(pycurl.URL, url)crl.setopt(crl.WRITEFUNCTION, crl.fp.write)crl.perform()print crl.fp.getvalue()

說Python開發快的都是廢話,這能不快嘛!!!!!!
