How to detect line separator and line break in python csv

Here is how I'm detecting a field separator and line break in a csv file for which I do not already know the format. Does this look sufficient, or are there other things I should be adding here?



SEPARATORS=['x00', 'x01',  '^', ':', ',', 't', ':', ';', '|', '~', ' ']
LINE_TERMINATORS_IN_ORDER = ['x02n', 'rn', 'n', 'r']

def get_csv_info(file)
with open(f, 'r') as csvfile:
line = next(csvfile)
dialect = csv.Sniffer().sniff(line, SEPARATORS)
for _terminator in LINE_TERMINATORS_IN_ORDER:
if line.endswith(_terminator):
terminator = _terminator
break

return (dialect.delimiter, terminator)


Note: using the normal csv.Sniffer without params fails most of the time I use it.
