New submission from Martin Budaj :
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>[^\w\n"\'])(?P ?)(?P["\
Martin Budaj added the comment:
Units test and two patches for 2.7 are included.
p1.patch fixes testEnd case reported yesterday
After running unittest it seems that also other case is broken (testAl -- if
there is just one data item on the line, enclosed in quotes). Patch p2 fixes
it, but
Martin Budaj added the comment:
I'm not sure about what the intended behavior for testAl should be, however I
think that the file should be recognized as having one column of data and no
delimiter (there is a test for this case in csv.py) and not raise an exception.

I meant test in regex on line 217 in python 2.7 and the following code (line
258ff):
# there is *no* delimiter, it's a single column of quoted data
delim = ''
