This article's quality is questionable. Right from the start, it incorrectly links to the Python version 2 collections module documentation. The article content doesn't vary much from what you'd find in the documentation if it does so at all save for changing the names of variables, values, etc.. Other parts seem handwavy at best. The "Conclusion" is just bizarre. The Python documentation for the collections module[1] is actually quite good. The page offers the usual API documentation as well as a fair amount of examples for each component.
