🐍 Python Pattern Challenge — Day 39 | Hollow Hourglass Star Pattern

Welcome to Day 39 of the Python Pattern Challenge! 🚀

Today, we're exploring a creative Hollow Hourglass Star Pattern using Python. This design combines expanding star rows with hollow sections to create an interesting geometric shape.

Pattern printing is a great way to improve your understanding of loops, nested loops, spacing, and logical thinking. Even a simple symbol like * can create fascinating designs when arranged with the right logic!

🎯 Today's Challenge

Write a Python program to print the following pattern:

💻 Python Solution

n = 5

# Upper section
for i in range(1, n + 1):
    print("  " * (n - i) + "* " * (2 * i - 1))

# Middle hollow section
for i in range(n, 0, -1):
    print("  " * (n - i) + "* " * i + "  " * (n - i) + "* " * i)

# Lower section
for i in range(n - 1, 0, -1):
    print("  " * (n - i) + "* " * (2 * i - 1))

🧠 What You'll Learn

1. Nested loops: Understand how loops control rows and columns.

2. String repetition: Use the * operator to repeat stars and spaces.

3. Spacing and alignment: Control the position of each star to create geometric designs.

4. Pattern logic: Learn how increasing and decreasing sequences build symmetrical shapes.

5. Problem-solving: Break a complex-looking pattern into smaller sections.

🚀 Challenge Yourself

• Increase the pattern size.

• Replace stars with numbers or alphabets.

• Create a completely hollow diamond.

• Try using nested loops instead of string repetition.

• Take the pattern size as input from the user.

Keep practicing and challenge yourself to write the solution without looking at the code!
