The part outside the innermost loop gets printed fine, but the part within the innermost loop doesn't get printed. I get an error: 'str' has no attribute 'write'. Thanks in advance.

The above isn't Python so please post all of your code or a 
representative snippet that can show the problem, with the complete 
traceback and not simply the last line.  Having said that I'm guessing 
that you're reassigning f somewhere to be a string, hence the error. 
Also why not write Python loops like:-
for r in name:
     etc.
