试图理解 Python Beautiful Soup 解析代码

Question

我遇到了以下代码，我发现它非常有用，但不确定如何解释其中的一段。

from pprint import pprint
import urllib2
from bs4 import BeautifulSoup

url = 'http://en.wikipedia.org/wiki/List_of_Bollywood_films_of_2014'
soup = BeautifulSoup(urllib2.urlopen(url))

headers = ['Opening', 'Title', 'Genre', 'Director', 'Cast']
results = {}

for block in soup.select('div#mw-content-text > h3'):
    title = block.find('span', class_='mw-headline').text
    rows = block.find_next_sibling('table', class_='wikitable').find_all('tr')

    results[title] = [{header: td.text for header, td in zip(headers, row.find_all('td'))}
                      for row in rows[1:]]

pprint(results)

除了这一段我都懂了:

    results[title] = [{header: td.text for header, td in zip(headers, row.find_all('td'))}
                      for row in rows[1:]]

谁能解释一下这是做什么的以及我应该如何阅读它？谢谢！

Answer 1

那一行基本可以分解成这样

for count, row in enumerate(rows[1:]):
    for header, td in zip(headers, row.find_all('td'):
        results[title][count][header] = td.text
