[Python-ideas] Context manager for csv module 'reader' and 'DictReader'?
Hi all, the product of Sunday morning idle curiosity... I’ve been using the csv module a lot, and I’m wondering if there would be value in adding a standard mechanism for opening a CSV file (correctly) using a context manager? So, instead of with open(filename, newline=“”) as fp: r = csv.DictReader(fp) for row in r: … support something like with csv.DictReader.open(filename) as r: for row in r: … ? And something similar for ‘csv.reader’? I’m not wedded to the details here. The two main reasons I think this might be a positive addition are - * you wouldn’t have to know or remember the right way to open a CSV file (newline=“”). * it elides very common code. but perhaps there are things I’m missing here? As a side note, I think ‘csv.reader’ could usefully be renamed to something else (maybe just Reader?), since it’s kind of out of sync with the CamelCase used in ‘DictReader’. But maybe that’s just an attempt at foolish consistency :). best, —titus ___ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/EKHYCTYMXZG3VI4JYFA3Y3LD3ZNMI3IX/ Code of Conduct: http://python.org/psf/codeofconduct/
[Python-ideas] Re: Context manager for csv module 'reader' and 'DictReader'?
Thanks for your comments, everyone! Right, I’m struggling to figure out Greg's example :). Maybe Greg missed that DictReader.open didn’t exist and was in fact what I was asking for! (contextlib.closing is great, thank you for that!) Anyway, just to re-up the original points and add a few - * opening a CSV file with the right newline setting and then applying csv.reader and csv.DictReader is super common. * newline=“” has important ramifications for Windows functionality, as we recently discovered when we tried to extend sourmash with windows compat. * yes it’s very easy to write my own utility function to do this, and in fact I have done so …repeatedly. :) * no one is proposing to remove any functionality. * I like Chris Barker’s comment, “”” it ended with the idea that maybe there should be a PEP for a common interface for all “file” readers — eg JSON, CSV, etc.. And that interface could be supported by third party libs. That interface *maybe* would include a single step load from a path-like functionality. “”” I’m +0 on David Mertz’s suggestion, “”" Most Pandas read methods take either a path-like argument or a file-like argument, and figure out which it is by introspection when called. Actually, most of them even accept a URL-like argument as well I don't think this is a terrible approach. It doesn't make things quite as explicit as the standard library generally does. But it's convenient, and there's no real ambiguity. “”” mostly because when we’ve done this in our own packages, I've struggled to figure out the best method to figure out if something is file-like. For example, it looks like ‘csv.DictReader’ will take any iterable, which means passing in a string is problematic; perhaps we could be looking for read or readline instead? Codifying that in some standard way could be nice. best, —titus > On Sep 5, 2021, at 5:30 PM, Oscar Benjamin wrote: > > On Mon, 6 Sept 2021 at 01:13, Greg Ewing wrote: >> >> On 6/09/21 3:07 am, C.

Hi all, python-ideas moderator here. It’d be great if y’all could take a few days to cool off the frozen set discussion, which is veering off the rails a little bit into emotional language. I’ll keep an eye on it and put emergency moderation into effect if I must, but it’d be nicer if I didn’t feel the need to do that. thanks, —titus ___ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/W5MS2FTUMSKYIFXDPPYJPIS3CFW43JYP/ Code of Conduct: http://python.org/psf/codeofconduct/

My two cents (speaking as long-term observer, not as the moderator, or perhaps in addition to the moderator ;) - I think your ask was appropriate, and I think the response of “here’s the search you should do!” was great. Personally I think we could do without the implication that you should have done more due diligence. python-ideas is PRECISELY for this kind of question.
