【python】如何下载一个网页

Stackoverflow的答案：
http://stackoverflow.com/questions/22676/how-do-i-download-a-file-over-http-using-python

import urllib2response = urllib2.urlopen('http://www.example.com/')html = response.read()

import urlliburllib.urlretrieve ("http://www.example.com/songs/mp3.mp3", "mp3.mp3")

还有如progress bar的实现等等。
2012的requests，对http直接封装：

>>> import requests>>> >>> url = "http://download.thinkbroadband.com/10MB.zip">>> r = requests.get(url)>>> print len(r.content)10485760

各类回答棒极了
