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.

Please post your exact actual code (which this isn't; it has clear
fatal syntax errors) and the full error message, including the stack
Traceback.

I would suspect there is some problematic assignment to `f` that you
excluded from the snippet you posted.

Cheers,
