Somewhat to my surprise, in Python 2.6,

with urllib2.urlopen(url) as fh :

doesn't work. It fails with
"AttributeError: addinfourl instance has no attribute '__exit__'".

I thought that all the file-like objects supported "with" in 2.6.
No?

I guess not. Use contextlib.closing.

This seems to work in 3.1, which first came out almost a year after 2.6.

from urllib.request import urlopen
with urlopen("http://www.python.org") as fh : pass
