Cheryl Sabella added the comment: Thank you. I've added that. This may seem like an odd question, but should I assume that the docs should always match the code? For example, in the Functional HOWTO, I wasn't sure if the arguments were left off purposely or if it was just something that hadn't been updated. If the docs should always match, then I wouldn't have to ask so many questions if I see another place where this happens. Also, the example for enumerate is this: f = open('data.txt', 'r') for i, line in enumerate(f): if line.strip() == '': print('Blank line at line #%i' % i) Is it code churn to replace the old style string formatting or is that something else that should be done as clean-up? ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue30538> _______________________________________
