**File "ProjetVinNicolas3\spiders\nicolas_spider3.py", line 70, in parse_wine_page
classement, appelation, couleur = res.select('.//div[@class="pro_col_right"]/div[@class="pro_blk_trans"] div[@class="pro_blk_trans_titre"]/text()').re(r'^(\d\w+\s*Vin)\S\s+(\w+-\w+|\w+)\S\s+(\w+)\s*$')
exceptions.ValueError: need more than 0 values to unpack**
