The error you're hitting happens because the facebook package you installed is Python 2-only—it uses outdated syntax that’s no longer valid in Python 3. Here’s how to resolve this:

Root Cause #

The line except urllib2.HTTPError, e: is classic Python 2 syntax. In Python 3:

• Exception handling uses as instead of a comma (e.g., except urllib.error.HTTPError as e:)
• The urllib2 module was split into urllib.request and urllib.error, so urllib2 doesn’t exist natively anymore.

The original facebook package on PyPI hasn’t been updated for Python 3 compatibility, which is why reinstalling it didn’t fix the issue.

Solution Steps #

1. Uninstall the outdated package:
   Run this command in your terminal to remove the Python 2-only version:

   pip uninstall facebook
   

   Confirm the uninstallation when prompted.

2. Install the Python 3-compatible Facebook SDK:
   The official, maintained Facebook SDK for Python is available as facebook-sdk on PyPI. Install it with:

   pip install facebook-sdk
   

3. Keep your existing code:
   The facebook-sdk package uses the same module name, so your original import code works without changes:

   import requests
   import facebook
   

This should eliminate the syntax error, as the facebook-sdk package is fully optimized for Python 3.
