Python Pandas read_html() Error: HTTP Error 404: Not Found

This error message indicates that the code is trying to access a webpage that does not exist (HTTP Error 404: Not Found). It could be due to a mistyped URL or the webpage being removed or relocated.

Here's a breakdown of the error and possible solutions:

• HTTP Error 404: Not Found: This standard HTTP status code signifies that the requested resource (webpage) could not be found on the server.
• Mistyped URL: Double-check the URL in your pd.read_html(url) call for any typos or inconsistencies. Make sure the URL is correct and points to the intended webpage.
• Removed or Relocated Webpage: The webpage you're trying to access might have been removed or moved to a different location. Try searching for the webpage online to see if it's available elsewhere. If the webpage has been moved, update your code with the new URL.

How to fix the error:

1. Verify the URL: Carefully inspect the URL you're providing to pd.read_html() to ensure it's accurate and hasn't changed.
2. Check Webpage Availability: Go to the URL in your browser to verify if the webpage exists. If it's gone, search for it online to see if it's been relocated.
3. Use the requests library for more control: If the issue persists, you can switch to the requests library to handle web requests. It provides more detailed information about errors, including error codes and response content.

Example using requests:

import requests
import pandas as pd

url = 'https://www.example.com/table'  # Replace with the actual URL
response = requests.get(url)

if response.status_code == 200:
    dfs = pd.read_html(response.text)
    # Process the extracted tables
else:
    print(f'Error: {response.status_code} - {response.reason}')
