http://docs.python.org/py3k/library/urllib.request.html#urllib.request.urlopen Specifically: "This function returns a file-like object" (representing the stream of data received). Thus, .read() on the file-like object returns the actual bytes obtained from the given URL. Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
