Function Extraction:

I created separate functions (check_project_slug, check_author_name, etc.) to encapsulate specific checks. This makes the code more modular and readable.

Function Parameters:
I modified the functions to take parameters instead of using global variables directly. This enhances reusability and makes the functions more flexible.

Input Function:
I replaced raw_input() with input() to ensure compatibility with both Python 2 and 3, as the input() function serves the same purpose in Python 3.

Encapsulation of Main Checks:
The main logic for checking project_slug, author_name, Python version, Whitenoise, and mail service is now encapsulated within the __main__ block. This improves code organization and readability.

Readability and Clarity:
Variable names are more descriptive, improving the readability of the code.

Consistent Formatting:
I ensured consistent formatting and adhered to PEP 8 conventions for better style and consistency.
