漂亮汤错误:“NoneType”对象没有属性“find\u all”

什么时候 soup.find 没有找到任何东西,它返回 None s.find_all 呼叫 if s: 或 if s in not None: .

因此,您的代码变成:

r = requests.get('https://www.marketsandmarkets.com/Market-Reports/rocket-missile-market-203298804.html/')
soup = BeautifulSoup(r.content, 'html.parser')
s = soup.find('div', class_='entry-content') 
if s is not None:
    content = s.find_all('p')
    print(content) 
else:
    print("Didn't find what I was looking for...")

或者可能:

content = s.find_all('p') if s is not None else []
print(content)
