At the following url...
http://docs.python.org/library/urllib2.html
They have the following...
"urllib2.urlopen(url[, data][, timeout])
Open the URL url, which can be either a string or a Request
object"
I don't get how urllib2.urlopen() can take a Request object. When I do
the following....
[cdal...@localhost ~]$ python
Python 2.4.3 (#1, Oct 1 2006, 18:00:19)
[GCC 4.1.1 20060928 (Red Hat 4.1.1-28)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
import urllib2
url = 'http://www.google.com'
req = urllib2.Request(url)
response = urllib2.urlopen(req)
req is clearly an instance of urllib2.Request and not a Request object.
Yes -- it seems both the 'Request Object' and 'Request Instance' terms
are used.
If you feel it's a bug you can report this at http://bugs.python.org,
but I'm not sure what else an object would be if not an instance of a
class...

Help on module urllib2:
NAME
urllib2 - An extensible library for opening URLs
using a variety of protocols
FILE
c:\python24\lib\urllib2.py
DESCRIPTION
The simplest way to use this module is to call the
urlopen function, which accepts a string containing
a URL or a Request object (described below).
---------------^^^^^^^^^^^^^^
<snip 2 paragraphs>
urlopen(url, data=None) -- basic usage is that same
as original urllib. pass the url and optionally data
to post to an HTTP URL, and get a file-like object
back. One difference is that you can also pass a
Request instance instead of URL.
