使用 urllib.request 下载简单的 Web 内容

标准库模块 urllib.request 可用于下载 Web 内容：

from urllib.request import urlopen

response = urlopen('http://stackoverflow.com/questions?sort=votes')    
data = response.read()

# The received bytes should usually be decoded according the response's character set
encoding = response.info().get_content_charset()
html = data.decode(encoding)

Python 2 中也提供了类似的模块。
