Hi folks, I am looking for some tool (or algorithm which I can implement at the worst) which calculates similarities between strings.

There are many such algorithms, starting with the venerable Soundex algorithm, the well-known Levenshtein distance, and many more.

Feel free to propose anything, I have not done any research on this topic.

I propose that next time you do your research first. Here's a starting point for you:

The scipy package has several implementations of "distances". all of them are useful in one way to another to make these comparisons. Another package (related only for this topic) is https://pypi.org/project/textdistance/ I hope my contribution is not buried under a lot of "off-topics" El dom., 15 sept. 2019 a las 23:13, Stephen Satchell () escribió:

googling it? Probably not. I think we're all friendlier than that.

I don't know about others, but when I run into the same situation, instead of saying "just Google it" I provide a few links to get the asker a start. Been doing that, in one form or another, in one medium or another, for my entire 46-year career.

Back in the beginning, before the Internet, before ARPAnet, I would provide a few references for the person on a quest to look up in the library. Working on the theory that "give a person a fish, they eat for a day; teach them to fish and they eat forever."

If someone can't play nice, they should not play at all. We are all in this together, from retiree to greenhorn. _______________________________________________ code-quality mailing list -- code-quality@python.org To unsubscribe send an email to code-quality-leave@python.org https://mail.python.org/mailman3/lists/code-quality.python.org/

There was nothing sarcastic in my response. I meant every word of it exactly as I said it. I answered Alexander's question about string similarity, and gave a technically better answer than those who just named Levenshtein distance as if it were the only option. And I didn't *just* answer his question, I gently gave a mildly-worded answer: do your research first next time. I didn't insult him, or call him names, or even call him out for disrespecting everyone's time. It surely took Alexander much longer to type up his email and send it to the list than it would have taken him to google "string similarity". It is not just for our benefit, but his too, that he should do his own basic research before asking questions. -- Steven

Thank you to everyone who replied. I will check out all of the suggestions and post after some time with my findings or directly a linter plugin ready for use. -- Alex
