Do I need to call close on the handle returned by urlopen?

I think two things might be happening here.

1. Code samples are just that. They often demonstrate usage with the
smallest amount of code possible, so that the key part of what they
are demonstrating isn't lost in a bunch of other clutter. That often
means leaving out error checking and not completely cleaning up after
themselves, especially if those bits might obscure the actual concept
being conveyed.

2. The "with" statement is (relative to many other parts of the
language) still pretty new, so it's not all that surprising that
examples in the documentation haven't all been updated to reflect the
latest recommended practice.
