This would only be helpful when the CSV is on the disk but csv.reader() takes a file object so that it can used with anything like a socket for example. json.load() does the same thing.

There has been discussion about adding loading from a “path like” to the JSON lib. See this list about ten months ago and a recent thread on discuss.

There resistance, but 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.

It seems to me that it is better to keep a generic interface that are composable.

No one is suggesting removing the load-from-a-file-like interface. I have no idea why the fact that some people sometimes need a more flexible interface (maybe most people, even) somehow means that we shouldn’t make things easy and obvious for a common use case.

? 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,
