Code Improvements

[JohnKimaiyo]

Here's an improved version of the provided setup.py script for a Python package. This includes some enhancements for readability, error handling, and best practices:

Added error handling for reading requirements.txt.
Used setuptools.find_packages() to automatically discover packages.
Updated the Python version requirement to be more modern (>=3.6).
Used install_requires instead of dependency_links for better dependency management.
