Raymond Hettinger <[email protected]> added the comment:
Changing sniffer logic is risky because it risks breaking existing code that
relies on the current predictions.
FWIW, in your example, the sniffer gets the desired result if given a delimiter
hint:
>>> s = "a|b\nc| 'd\ne|' f"
>>> pprint.pp(dict(vars(Sniffer().sniff(s, '|'))))
{'__module__': 'csv',
'_name': 'sniffed',
'lineterminator': '\r\n',
'quoting': 0,
'__doc__': None,
'doublequote': False,
'delimiter': '|',
'quotechar': "'",
'skipinitialspace': False}
