beautifulsoupを使って、WEBサイトの中の、 X-path ='//*[@id="rankingChart"]/tbody/tr[22]/td'の中にある文字列をすべて取得する

def get_rank(url, tag, attribute, attribute_name, index_start, index_end):
  html = urllib.request.urlopen(url).read()
  soup = BeautifulSoup(html, "html.parser")
  rank = []
  for i in range(index_start, index_end):
    element = soup.select(tag)[i]
    rank.append(element[attribute])
  return rank

rank = get_rank(url, 'tr', 'class', '', 22, 27)
