🖼️ Python Pattern Drawing Project

Welcome to the Python Pattern Drawing Project! 🎉 This project is designed to help you understand and implement nested loops, conditional statements, and user inputs in Python.

---

📝 Project Overview

Your task is to create various patterns using Python's printing capabilities. You'll build a program where users can choose from different patterns, provide necessary inputs, and see the results displayed in the terminal.

---

🎯 Objectives

• Practice working with nested loops.
• Use if-elif-else conditions to implement logic.
• Handle user input to create dynamic patterns.
• Understand alignment using spaces and characters.

📋 Instructions

1️⃣ Run the Program
Start the program and choose a pattern from the menu.

2️⃣ Input Dimensions
Provide necessary inputs (e.g., number of rows or size of the shape).

3️⃣ See the Result
Enjoy the output directly in your terminal.

4️⃣ Try Again!
You can run the program again to explore different patterns.

🛠️ Code Skeleton

Below is the skeleton code with comments to guide you through the implementation. Your task is to fill in the missing parts and complete the program!

# 🖼️ Python Pattern Drawing Project

# Step 1: Display a menu to the user
print("🌟 Welcome to the Python Pattern Drawing Program!")
print("Choose a pattern type:")
print("1. Right-angled Triangle")
print("2. Square with Hollow Center")
print("3. Diamond")
print("4. Left-angled Triangle")
print("5. Hollow Square")
print("6. Pyramid")
print("7. Reverse Pyramid")
print("8. Rectangle with Hollow Center")

# Step 2: Get the user's choice
choice = int(input("Enter the number corresponding to your choice: "))

# Step 3: Get dimensions based on choice
if choice in [1, 3, 4, 6, 7]:  # Patterns that need the number of rows
    rows = int(input("Enter the number of rows: "))
elif choice in [2, 5, 8]:  # Patterns that need size
    size = int(input("Enter the size of the square/rectangle: "))

# Step 4: Generate the selected pattern
if choice == 1:  # Right-angled Triangle
    # TODO: Loop through rows and print increasing stars
    pass

elif choice == 2:  # Square with Hollow Center
    # TODO: Create a square with a hollow center
    pass

elif choice == 3:  # Diamond
    # TODO: Create a diamond shape using loops
    pass

elif choice == 4:  # Left-angled Triangle
    # TODO: Print decreasing stars for each row
    pass

elif choice == 5:  # Hollow Square
    # TODO: Similar to choice 2 but ensure perfect square logic
    pass

elif choice == 6:  # Pyramid
    # TODO: Center-align stars to form a pyramid
    pass

elif choice == 7:  # Reverse Pyramid
    # TODO: Create an upside-down pyramid
    pass

elif choice == 8:  # Rectangle with Hollow Center
    # TODO: Handle separate width and height inputs for rectangle
    width = int(input("Enter the width of the rectangle: "))
    height = int(input("Enter the height of the rectangle: "))
    pass

else:
    print("❌ Invalid choice! Please restart the program.")

# Step 5: Optional - Allow the user to restart or exit

🏁 Conclusion

By completing this project, you'll:

• Master nested loops to create complex patterns. 🌀
• Understand how to manipulate text alignment in Python. 📐
• Get hands-on experience with user inputs and conditional logic. 💻

This is a great stepping stone towards becoming proficient in Python programming. Enjoy your journey and have fun coding! 🚀

🌟 Bonus Ideas

• Add more patterns like spirals, checkerboards, or alphabets.
• Enhance the program to allow saving patterns as text files.
• Add color to the output using libraries like colorama.
