how to judge urllib.Request is finished?

[oyster]

currently I am using

req=urllib2.Request(url)
data=''
if '</htm>' not in data:
fd=urllib2.urlopen(req)
data=fd.read()
time.sleep(10)
time.sleep(10)
blahblah

Is there any other ready-to-use function? And what if the internet
connection is chocked so that the html page can not be loaded
entirely?

That looks very strange. Why the ``if`` and the `sleep()`\s? The ``if``
condition is always true, so it's completely unnecessary. The `read()`
call is blocking, that means it returns iff the complete data is read. So
there's no need to wait or to check if all is read. If there's a problem
with the connection an exception should be raised by `urllib2`.
