我是一個新的python。我想得到的代碼結果如下:使用python和美麗的湯從HTML獲取結構化數據
Score Postive Negative
5 good bad
7 interesting
3 horrible
但我的代碼輸出nothing.Please問題在哪裏?
from bs4 import BeautifulSoup
text = """
... <body>
<div class="review">
<p class="pos">good</p>
<p class="neg">bad</p>
</div>
<div class="review">
<p class="pos">interesting</p>
</div>
<div class="review">
<p class="neg">horrible</p>
</div>
... </body>"""
soup = BeautifulSoup(text)
for parent in soup.find_all('div', attrs={'class': 'review'}):
if parent.findNextSiblings('p', attrs={'class': 'pos'}):
postive.append(parent.get_text())
else:
postive.append("")
if parent.findNextSiblings('p', attrs={'class': 'neg'}):
negtive.append(parent.get_text())
else:
negtive.append("")
