It might be some ve= ry basic thing but I was wondering if someone could help. Its a loop within= a loop. The part outside the innermost loop gets printed fine, but the par= t 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, Chris
