I was seeing a lot of newline (^M) characters at the ends of the strings 
you posted.  When you concatenate them together then output them, the ^M 
may cause the lines to overwrite each other causing you to think you're 
only seeing the last one.  But repr turns these characters into a 
sequence of two characters, backslash followed by r.  Is this your 
problem?  If so, maybe you want to call strip() on your strings before 
concatenating or joining them?
