[New-bugs-announce] [issue10515] csv sniffer does not recognize quotes at the end of line

[Martin Budaj]

New submission from Martin Budaj <m.budaj at gmail.com>:

The method Sniffer._guess_quote_and_delimiter() in the module csv.py contains a bug in a regexp which checks for quotes around the last item of the line (example: a,b,"c,d"\n).

the pattern
'(?P<delim>>[^\w\n"\'])(?P<space> ?)(?P<quote>["\']).*?(?P=quote)(?:$|\n)'
used in the regex should be changed to
'(?P<delim>[^\w\n"\'])(?P<space> ?)(?P<quote>["\']).*?(?P=quote)(?:$|\n)'

file csv.py: line 212 in python 2.6, line 216 in 2.7, line 207 in 3.1
