Terry J. Reedy <tjre...@udel.edu> added the comment:
As I understand this, you are asking that 2.7 urllib2.build_opener().open(),
which in 3.x is urllib.request.build_opener().open(), be upgraded to return an
object that works as a context manager. Unless the docs say that this should
already be the case, this is a feature request for 3.3.
I am unable to test whether this feature is already present (in 3.2.2). Your
example line "with urllib2.build_opener().open() as:" has an obvious syntax
error. When I correct that and adjust for 3.x
import urllib.request as ur
with ur.build_opener().open() as f:
pass
#
TypeError: open() takes at least 2 arguments (1 given)
The doc for build_opener says it returns an OpenerDirector instance.
help(ur.OpenerDirector.open) just says it needs a 'fullurl'. But when I add
'http:www.python.org' as an argument, I get
urllib.error.URLError: <urlopen error no host given>
I do not know what else is needed.
Please copy and paste the ACTUAL (minimal) code you ran to get the
AttributeError.
