🐍 Python Pattern Challenge — Day 40 | Number Wave Pattern

Welcome to Day 40 of the Python Pattern Challenge! 🚀

Today, we're creating an interesting Number Wave Pattern using Python. This pattern starts with a complete number sequence, gradually reduces the numbers in each row, and then expands again to create a symmetrical wave-like design.

It's a simple but effective challenge to improve your understanding of loops, number sequences, spacing, and pattern-building logic.

🎯 Today's Challenge

Write a Python program to print exactly the following pattern:

💻 Python Solution

n = 5

for i in range(1, n + 1):
    print("  " * (i - 1), end="")
    print(*range(i, n + 1))

for i in range(n - 1, 0, -1):
    print("  " * (i - 1), end="")
    print(*range(i, n + 1))

🧠 How It Works

1. Creating the upper section

for i in range(1, n + 1):

This loop generates the first five rows, starting from 1 and increasing the starting number in each row.

2. Managing the spacing

print(" " * (i - 1), end="")

This adds leading spaces to shift each row toward the center.

3. Printing the number sequence

print(*range(i, n + 1))

The range() function generates numbers from the current value of i up to 5.

4. Creating the lower section

for i in range(n - 1, 0, -1):

This loop reverses the process, gradually restoring the complete number sequence.

🚀 Challenge Yourself

• Increase the pattern size to 7.

• Replace numbers with alphabets.

• Create an inverted version of this pattern.

• Try implementing the same pattern using a while loop.

• Take the maximum number as input from the user.

The best way to improve your Python logic is to practice small challenges and experiment with different patterns.
