Why doesn't the parser code work?

Question

Python

if I display the title and the price, it works, but if I add a picture, it displays an empty list

re = requests.get('http://books.toscrape.com')
html = re.text
soups = ba(html, 'lxml')
aa = [(title.string, price.string, images['src']) for title in soups.section.find_all('h3') 
for price in title.find_parents()[0].find('p', class_='price_color')
for images in title.find_parents()[0].find('img')]
print(aa)
