Program to create a pyramid of stars.
Reviewer's GuideAdds a new pyramid_of_stars.py script that interactively builds and prints a centered star pyramid using modular functions for input validation and pattern generation. Class diagram for pyramid_of_stars.py functionsclassDiagram

Hey there - I've reviewed your changes - here's some feedback:
- Consider simplifying the star generation by using '' * (2 * i - 1) for each row instead of ' ' * i and rstrip to avoid trailing spaces more directly.
- For greater flexibility and ease of automation, consider adding an optional command-line argument (via argparse) for the number of rows instead of relying solely on interactive input.
- The diff shows an unintended duplicate entry (“Pyramid of stars”) after the main script – please remove or correct it so only the intended .py file is added.

**suggestion:** Consider handling KeyboardInterrupt to allow graceful exit.
Currently, pressing Ctrl+C results in an unhandled exception. Catching KeyboardInterrupt would allow the program to exit cleanly.

This pull request introduces a new Python script named pyramid_of_stars.py that prints a beautiful pyramid pattern made of stars (*) based on user input.
The script is simple, interactive, and designed to demonstrate the fundamentals of loops, string formatting, and user input handling in Python.
It is a perfect beginner-friendly contribution for learning pattern generation and console output formatting.
