Web scraping is a process of extracting data from websites. Python has become one of the most popular programming languages for web scraping. However, when trying to retrieve data from a website that uses HTTPS protocol, you may encounter a Certificate_Verify_Failed error. This error can be frustrating, as it can hinder your web scraping project. But, there is no need to worry, as in this article we will guide you on how to fix this issue easily.
Understanding Certificate_Verify_Failed Error
Certificate_Verify_Failed error occurs when a website’s SSL/TLS certificate cannot be verified by Python. SSL/TLS certificates are used to ensure secure connection between a client and a server. Python checks whether a site’s SSL/TLS certificate is valid before initiating a connection. If the certificate is invalid or has expired, the connection is not established, and Certificate_Verify_Failed error is displayed.
Methods to Fix Certificate_Verify_Failed Error
Method 1: Ignore Certificate Errors
You can tell Python not to verify SSL/TLS certificate while making a request to a website. This is not a recommended method, as it bypasses the security checks, but it can be useful if you are sure that the website you are accessing is safe. You can do this by adding the following code:
|To Ignore SSL/TLS errors
|To verify SSL/TLS certificate
from requests.packages.urllib3.exceptions import InsecureRequestWarning
response = requests.get(https://example.com, verify=True)
Method 2: Install SSL/TLS Certificates
You can also install the SSL/TLS certificates on your system. SSL/TLS certificates are issued by Certificate Authorities (CA), and there are many CA’s available. You can obtain a certificate from a trusted CA, and install it on your operating system. This will ensure that Python can verify the SSL/TLS certificates of websites you access.
Method 3: Update Requests Module
You can update the ‘requests’ module used to make web requests. This will ensure that the latest SSL/TLS certificate authorities are used by Python. To update the module, run the following command:
pip install requests[security]
Method 4: Use OpenSSL
You can use OpenSSL library to verify the SSL/TLS certificates. OpenSSL is an open-source implementation of the SSL/TLS protocol. To use OpenSSL with Python, you must install pyOpenSSL module. Then, you can make a request using OpenSSL by passing
ssl_context parameter as shown below:
from OpenSSL import SSL
context = SSL.Context(SSL.SSLv23_METHOD)
response = urllib.request.urlopen('https://www.example.com', context=context)
html = response.read()
Certificate_Verify_Failed error can be a hindrance to your web scraping project. However, with the above methods, you can easily fix this issue. If you are concerned about security, then the second and third method are recommended. By installing SSL/TLS certificates or updating the ‘requests’ module, you can ensure that Python uses the latest and trusted SSL/TLS certificate authorities. If you are sure that the website is safe, then you can use the first method to ignore SSL/TLS errors.

As a language model AI, I cannot provide personal opinions or experiences. However, based on research and relevant sources, here are some possible people also ask questions about Python Tips: How to Fix Certificate_Verify_Failed Error When Scraping HTTPS://www.thenewboston.com/:
1. Why am I getting a Certificate_Verify_Failed error when scraping from thenewboston.com using Python?
If you encounter this error, it means that the SSL certificate of the website is not recognized or trusted by your Python environment. This can happen if the website has a self-signed certificate, an expired certificate, or if the certificate authority is not listed in your system’s trust store.
2. How can I fix the Certificate_Verify_Failed error in Python?
There are several ways to address this issue:
- Disable SSL verification by passing the argument verify=False in your requests.get() function. However, this is not recommended as it poses security risks.
- Update your system’s trust store by installing the necessary certificates or adding the certificate authority to the list of trusted CAs.
- Use a third-party library like certifi to manage SSL certificates in Python.
3. Are there any other common errors when scraping websites with Python?
Yes, other common errors include HTTP errors (e.g. 404, 500), timeouts, and CAPTCHA challenges. To handle these errors, you can use try-except blocks and retry mechanisms in your code.
4. What are some best practices for web scraping with Python?
Some best practices include respecting a website’s terms of service, avoiding excessive requests that may overload the server, and using user-agent headers to mimic a browser’s behavior. It is also important to handle errors gracefully and to clean and validate the scraped data before using it.
