使用beautifulsoup從一張表中抓取時出現Web抓取問題

Question

import requests
from bs4 import BeautifulSoup
page = requests.get('http://www.freejobalert.com/ap-govt-jobs/144586/')
c = page.content
soup = BeautifulSoup(c,"html5lib")
row = soup.find_all("table")[0].find_all('tr')
dict = {}
for i in row:
    for title in i.find_all('span', attrs={'style':'color: #008000;'}):
        dict['Title'] = title.text
    for link in i.find_all('a',title=True, href=True):
        dict['Link'] = link['href']
        print(dict)

在這里，我得到的數據為空：

我期望：

{'Link': 'http://www.freejobalert.com/wp-content/uploads/2018/08/Detailed-Notification-Directorate-of-Public-Health-Family-Welfare-Vijayawada-Civil-Assistant-Surgeon-Posts.pdf', 'Title': 'Detailed Notification'}
{'Link': 'http://www.freejobalert.com/wp-content/uploads/2018/08/Notification-Directorate-of-Public-Health-Family-Welfare-Vijayawada-Civil-Assistant-Surgeon-Posts.pdf', 'Title': 'Notification '}
{'Link': 'http://cfw.ap.nic.in/', 'Title': ' Official Website'}

在這里，我只從第一個表中抓取數據。 但這給了我所有表的數據。我只想要第一個表的重要鏈接。 但這給了我兩個。 請看一下我的代碼。

我測試了您的代碼，它對我來說運行正常，但是我將dict的名稱更改為some_dict，如下所示：

import requests
from bs4 import BeautifulSoup
page = requests.get('http://www.freejobalert.com/ap-govt-jobs/144586/')
c = page.content
soup = BeautifulSoup(c,"html5lib")
row = soup.find_all("table")[0].find_all('tr')
some_dict = {}
for i in row:
    for title in i.find_all('span', attrs={'style': 'color: #008000;'}):
        some_dict['Title'] = title.text
    for link in i.find_all('a', title=True, href=True):
        some_dict['Link'] = link['href']
        print(some_dict)

由於它掩蓋了Python的內置dict類。 我的輸出是：

{'Title': 'Detailed Notification', 'Link': 'http://www.freejobalert.com/wp-content/uploads/2018/08/Detailed-Notification-Directorate-of-Public-Health-Family-Welfare-Vijayawada-Civil-Assistant-Surgeon-Posts.pdf'}
{'Title': 'Notification ', 'Link': 'http://www.freejobalert.com/wp-content/uploads/2018/08/Notification-Directorate-of-Public-Health-Family-Welfare-Vijayawada-Civil-Assistant-Surgeon-Posts.pdf'}
{'Title': ' Official Website', 'Link': 'http://cfw.ap.nic.in/'}

如果將dict重命名為其他名稱，它可以運行嗎？
