I don't know why the error, it suggests the data file is corrupted.
You may need to fetch another copy. Make sure you save the file rather 
than try to open it so that it downloads in binary format or it may be 
truncated...


However, having downloaded it I'm not sure why you are specifying the 
filename with /// at the front. It looks like you are on Linux? You 
should only need

file=open('/Users/joebatt/Desktop/banner.p.webarchive','rb')

But that shouldn't really make any difference to the end result.
