Not really when the "Introduction to Dictionaries", which doesn't belong on an article about how to iterate through them, is 20 paragraphs long. If you want to write an article on Python dictionaries, sure spend 20 paragraphs on it. But don't title the article "How to iterate through a dictionary" I'm surprised they didn't spend another twenty describing the origination of term iterate from the original Latin 'iterum'.
