我從運行代碼中得到一個意外的關鍵字引數。來源：https : //sempioneer.com/python-for-seo/how-to-extract-text-from-multiple-webpages-in-python/ 有人可以幫忙嗎？謝謝
運行以下代碼：
single_url = 'https://understandingdata.com/'
text = extract_text_from_single_web_page(url=single_url)
print(text)
給出以下錯誤：

uj5u.com熱心網友回復：
正如我在評論中所建議的，最好的選擇是找到一個不使用 的教程trafilatura，因為這似乎是壞事。但是，修改此特定函式以避免它并使用回退非常簡單：
def extract_text_from_single_web_page(url):
try:
resp = requests.get(url)
# We will only extract the text from successful requests:
if resp.status_code == 200:
return beautifulsoup_extract_text_fallback(resp.content)
else:
# This line will handle for any failures in the BeautifulSoup4 function:
return np.nan
# Handling for any URLs that don't have the correct protocol
except MissingSchema:
return np.nan
