Senthil:
http://docs.python.org/dev/library/contextlib.html#contextlib.closing
currently has this example:
from urllib.request import urlopen
with closing(urlopen('http://www.python.org')) as page:
which is misleading in that the object returned from urlopen
<class 'http.client.HTTPResponse'>
has __enter__ and __exit__ methods and therefore is a c.m. in itself and does
not need to be wrapped in closing(). I did not really understand from your
comment whether there is any need to use closing() with anything returned in
urllib.
At the moment, shelves are not C.M.s, and would make better examples, but
#13896 suggests 'fixing' that also.
