Installer win32api dans un virtualenv :



I found http://old.nabble.com/Windows:-virtualenv-and-pywin32--td27658201.html (now a dead link) which offered the following solution:

   Browse http://sourceforge.net/projects/pywin32/files/ for the URL of the exe you want
   Activate your virtualenv
   Run easy_install http://PATH.TO/EXE/DOWNLOAD

This works with modern versions of setuptools (circa February 2014, reported by tovmeod in the comments).

/*I usually just use urllib.urlretrieve(). It works, but if you need to use a session or some sort of authentication, the above code works as well.*/

Get a file-like object from the request and copy it to a file. This will also avoid reading the whole thing into memory at once.

import shutil
import requests

url = 'http://example.com/img.png'
response = requests.get(url, stream=True)
with open('img.png', 'wb') as out_file:
   shutil.copyfileobj(response.raw, out_file)
del response
########################

Note that the .raw file-like object does not decompress a response using Content-Encoding: gzip or Content-Encoding: deflate. You can use response.raw.read(decode_content=True) but shutil.copyfileobj cannot do that because it assumes a generic .read() method
