I'm a bit baffled by something...
In a script I wrote, I have defined a function that runs
urllib2.urlopen() on a urllib2.Request object and returns the file-like
object. The code that calls this function attempts to build a
csv.DictReader object based on that file-like object, but an error is
thrown saying the file-like object is not an iterator.
I could have sworn urllib2.urlopen returned an iterator, so I tested:
Python 2.3 (#1, Sep 13 2003, 00:49:11)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib2
>>> r = urllib2.Request('http://www.google.com')
>>> ifs = urllib2.urlopen(r)
>>> dir(ifs)
['__doc__', '__init__', '__iter__', '__module__', '__repr__', 'close',
'fileno', 'fp', 'geturl', 'headers', 'info', 'next', 'read',
'readline', 'readlines', 'url']
Yep. But what about in my code? I modify my code to print dir(ifs)
before creating the DictReader...
['__doc__', '__init__', '__module__', '__repr__', 'close', 'fp',
'geturl', 'headers', 'info', 'read', 'readline', 'url']
Traceback (most recent call last):

Whoa! Where did the __iter__, readlines, and next attributes go? Ideas?
