I tried to download something from the Internet using Python, I am using urllib.retriever from the urllib module but I just can't get it work. I would like to be able to save the downloaded file to a location of my choice. If someone could explain to me how to do it with clear examples, that would be VERY appreciated.

推荐答案

我建议使用 urllib2 像这样:

I suggest using urllib2 like so:

source = urllib2.urlopen("http://someUrl.com/somePage.html").read()
open("/path/to/someFile", "wb").write(source)

您甚至可以将其缩短为(尽管，如果您计划将每个单独的调用包含在 try - except 中，您不会想要缩短它):

You could even shorten it to (although, you wouldnt want to shorten it if you plan to enclose each individual call in a try - except):

open("/path/to/someFile", "wb").write(urllib2.urlopen("http://someUrl.com/somePage.html").read())
