Download and Save a file in python 2.7?

问题

Coming from here:

Basic http file downloading and saving to disk in python?

Is there any possibility to save the file in any folder? I tried this but i get error:

IOError: [Errno 2] No such file or directory:

import urllib

testfile=urllib.URLopener()
testfile.retrieve("http://randomsite.com/file.gz","/myfolder/file.gz")

Any possibility to do it?

回答1:

You're most likely getting that error because /myfolder doesn't exist. Try creating it first

import os
import os.path
import urllib

destination = "/path/to/folder"
if os.path.exists(destination) is False:
    os.mkdirs(destination)
# You can also use the convenience method urlretrieve if you're using urllib anyway
urllib.urlretrieve("http://randomsite.com/file.gz", os.path.join(destination, "file.gz"))

回答2:

The directory /myfolder/file.gz doesn't available in your server or pc. Make a real file path which exists in your pc or server. For example:

./file.gz
file.gz

This will save the file from where you are running your script. In other words, in the same location to your python script.
