Summary: Examples for urllib2

Initial Comment:
An associate who&#039;s learning Python recently complained
about a lack of
examples for urllib2.  As a starting point, I&#039;d like to
submit the
following:

This example gets the python.org main page and displays
the first 100 bytes
of it:

   >>> import urllib2
   >>> url = urllib2.urlopen(&#039;http://www.python.org/&#039;)
   >>> print url.read()[:100]
   <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN">
   <html>
   <!-- THIS PAGE IS AUTOMATICAL
   >>>

Here we are sending a data-stream to the stdin of a CGI
and reading the
data it returns to us:

   >>> import urllib2
   >>> req = urllib2.Request(url =
&#039;https://localhost/cgi-bin/test.cgi&#039;,
   ...       data = &#039;This data is passed to stdin of
the CGI&#039;)
   >>> url = urllib2.urlopen(req)
   >>> print url.read()
   Got Data: "This data is passed to stdin of the CGI"
   >>>

The code for the sample CGI used in the above example is:

   #!/usr/bin/env python
   import sys
   data = sys.stdin.read()
   print &#039;Content-type: text-plain\n\nGot Data: "%s"&#039; %
data

Since Fred said he checked in the examples here last year, 
and there is no other actionable item in this patch report, 
closing it now.

Please see 798244 -- I've uploaded some more examples 
there.

I've committed the examples from the patch in a slightly
modified form to Doc/lib/liburllib2.tex revisions 1.8 and
1.6.8.2.

Additional examples would be really helpful; especially
demonstrating the authentication support, as noted in the
comment from "fresh".

The examples for urllib2 are still really lacking :-(

I want to open an http basic auth protected URL and check
whether or not I get a 404 back. I have no idea hwo to do
that given the current documentation...
