我當前的代碼將 CSV 寫入多個單元格（請參閱屏幕截圖）from bs4 import BeautifulSoupimport csvimport urlliburl = 'https://www.bhphotovideo.com/c/product/1346734-REG/canon_eos_6d_mark_ii.html'page = urllib.request.urlopen(url)soup = BeautifulSoup(page,'lxml')content = soup.find('div', class_='js-productHighlights product-highlights c28 fs14 js-close')bullets = content.find_all('li', class_='top-section-list-item')csv_file = open('book2.csv', 'w')csv_writer = csv.writer(csv_file)csv_writer.writerow (['headline'])for bullet in bullets:     headline = (bullet.string)     csv_writer.writerow ([headline])csv_file.close()如何將excel寫入單個單元格？所需的輸出將是 - 單元格 A1 將包含變量“標題”包含的所有文本。
