Added Pyramid of Stars Python Script

[Saurabh6266]

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.

🚀 Features

• Prompts the user to enter the number of rows.
• Prints a centered pyramid pattern using nested for loops.
• Automatically adjusts spacing to maintain symmetry.
• Clean, well-commented, and formatted for readability.
• Requires no external dependencies — runs on standard Python 3.

💻 Code Overview The core logic uses:

• input() to capture user input.
• A for loop to iterate through each row.
• String multiplication and alignment for formatting each line.

🧠 Concepts Demonstrated

• Nested loops
• String concatenation and alignment
• Basic pattern printing logic
• User interaction through console I/O

🧾 Example Output Enter number of rows: 5 *

        "Print centered pyramid of stars"
    }
    class main {
