New submission from ejacq <0pyth...@jesuislibre.net>:
Here is an sample of CSV input: "time","forces" 0,0 0.5,0.9 when calling has_header() from csv.py on this sample, it returns false. Why? because 0 and 0.5 don't belong to the same type and thus the column is discarded by the heuristic. I think the heuristic will better work if rather than just comparing number types, it would also consider casting the values in this order int -> float -> complex. If the values are similar then consider this upgraded type as the type of the column. In the end, this file would be considered float columns with headers. ---------- components: Library (Lib) messages: 389515 nosy: ejacq priority: normal severity: normal status: open title: CSV has_headers heuristic could be improved versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43625> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
