running below code :

single_url = 'https://understandingdata.com/'
text = extract_text_from_single_web_page(url=single_url)
print(text)

gives below error :

CodePudding user response：

As suggested in my comment, the best option is to find a tutorial that doesn't use trafilatura, since that seems to be the thing that's broken. However, it's pretty simple to modify this particular function to avoid it and just use the fallback:

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
