Improvements

[ash-raph]

In this PR, I have accomplished the following:

• Split the data access from the script logic
  • This will enhance the readability since the logic will be clear on all sides
  • Easy to handle issues and exceptions
  • Allow multiple developers to work on the project -avoid conflicts-
• Split the setting in a separate file
  • This will enhance the readability
  • Make the setting more controlled from environment file
• Add tests
  • Ensure the code is working fine
  • Using mocks and freezegun allowed us to test all methods in the project
• Enhance dev environment
  • By adding gitignore, pipenv and pre-commit, will enhance the code quality and the code is running in all environments
