Hi, would something like the following pattern fulfill the requirements? (It doesn't handle possible empty fields, as mentioned in other posts, the surrounding whitespace can be removed separately: >>> >>> re.findall(r'(?:(?:"[^"]*"|[^,]))+(?=,|$)', 'aaaaa,bbbbb,ccccc >>> "4873898374", ddddd, eeeeee "3343,23,23,5,,5,45", fffff >>> "5546,3434,345,34,34,5,34,543,7"') ['aaaaa', 'bbbbb', 'ccccc "4873898374"', ' ddddd', ' eeeeee "3343,23,23,5,,5,45"', ' fffff "5546,3434,345,34,34,5,34,543,7"'] >>> >>> for field in re.findall(r'(?:(?:"[^"]*"|[^,]))+(?=,|$)', 'aaaaa,bbbbb,ccccc >>> "4873898374", ddddd, eeeeee "3343,23,23,5,,5,45", fffff >>> "5546,3434,345,34,34,5,34,543,7"'): print(field.strip()) ... aaaaa bbbbb ccccc "4873898374" ddddd eeeeee "3343,23,23,5,,5,45" fffff "5546,3434,345,34,34,5,34,543,7" >>> hth, vbr -- https://mail.python.org/mailman/listinfo/python-list
